What states are voting on Super Tuesday: Your ultimate guide to the biggest day of the primary election

The biggest day of the primary election season is finally here.

Thousands of voters from 15 states will head to the polls to cast their ballots on Super Tuesday in what could be the most consequential 24 hours of the Republican presidential race, especially for one candidate.

Will Donald Trump in a clean sweep of all the states? Can Nikki Haley possibly keep going if she has suffered a wave of defeats by the early hours of Wednesday morning? 

With 865 delegates up for grabs, Haley will likely make her last stand on Tuesday against the former president.

If she is unable to earn enough delegates to remain viable in the race, Tuesday could be the last nail in the coffin of her flailing campaign.

Before Tuesday, Iowa, New Hampshire, Nevada, South Carolina, Michigan, Idaho, Missouri and North Dakota, along with Washington DC and and the U.S. Virgin Islands already cast their ballots.

After these contests, Trump stands with 273 delegates to Haley's 43. The former United Nations Ambassador got a boost when she earned all 19 of the delegates from D.C. over the weekend.

This year, 15 states will vote on Super Tuesday: Alabama, Alaska, Arkansas, California, Colorado, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, Utah, Vermont and Virginia.

Ahead of Super Tuesday, Haley barnstormed some key states, including Virginia, North Carolina, Massachusetts, Vermont, Maine and Texas.

On Tuesday night, Haley plans to be in South Carolina – leading many to speculate that she will drop out of the race finally if the results of Super Tuesday don't sway her way and give her enough momentum to earn the 1,215 needed to clinch the GOP's presidential nomination.

Trump already handily defeated Haley in all four of the early primary states – including her home state of South Carolina – by double digits. And pro-MAGA world claimed no Republican would want to win D.C. after Haley's victory there.

Polls have Trump far ahead in most of the states set to vote, meaning many of the results could be lopsided.

DailyMail.com breaks down everything you need to know about Super Tuesday this year and what to watch as voters head to the polls.

Thousands of voters from 15 states will head to the polls for what has been known since the 1970s as 'Super Tuesday'

ALABAMA

Delegate Count: 50 – winner take most

Voting hours on Election Day: 7am to 7pm

Early in-person voting?: No

Open/Closed primary election?: Open. Voters can choose which party's ballot they wish to vote in. This decision does not register the voter with a political party.

Polling: A Morning Consult poll taken January 23-February 4 of likely voters in Alabama puts Trump a commanding 75 percent ahead of Haley (87 percent to 12 percent).

A deep red state in Trump country, Alabama is likely to have all their delegates go to the former president.

But Alabama has become the center of controversy regarding women's healthcare rights after a state Supreme Court ruling deemed fertilized eggs for IVF treatments are considered human life.

This resulted in IVF facilities in the state pausing operations amid discussion over how to handle the fertilized eggs with their new classification.

Alabama was one of more than a dozen states with trigger laws, meaning when the Supreme Court overturned Roe v. Wade in June 2022, abortion became essentially illegal. The state now has one of the most strict abortion laws in the country.

In both the 2016 and 2020 general elections, 62 percent of Alabama voted for Trump.

If the primary does not yield results with a candidate earning at least 51 percent of the vote, Alabama holds a runoff a few weeks later with the top two candidates on the ballot.

Since Trump and Haley are the only viable remaining candidates, it's likely Trump will walk away with considerably more than the required threshold to avoid a runoff.

Alabama held the fourth Republican presidential primary debate this cycle in Tuscaloosa on December 6 at the University of Alabama.

Haley was on the debate stage along with then-remaining 2024 rivals Florida Gov. Ron DeSantis, biotech entrepreneur Vivek Ramaswamy and former New Jersey Gov. Chris Christie.

Trump refused to participate in any primary debates.

Donald Trump was always the likely candidate for Republicans in 2024 – but after sweeping the first four primary states in January and February, his nomination became all but locked-up. Pictured: Trump speaks at a campaign rally in Waterford Township, Michigan on Feb. 17, 2024 

The University of Alabama hosted the fourth Republican presidential primary debate on Dec. 6, 2023 with former New Jersey Gov. Chris Christie, Haley, Florida Gov. Ron DeSantis and Vivek Ramaswamy. Trump refused to participate in primary debates

ALASKA

Delegate Count: 29 - proportional

Voting hours on Election Day: 7am to 8pm

Early in-person voting?: Yes, 15 days before Election Day.

Open/Closed primary election?: Alaska uses a pick-one primary election. It means all candidates, regardless of party, appear on a single ballot and voters choose one. The top four candidates who earn the most number of votes move onto the general election.

Polling: There appears to be no readily available polling for the presidential primary election in Alaska. But hypothetical general election match-ups from Alaska Survey Research conducted in October 2023 put Trump 8 percentage points ahead of President Joe Biden.

ARKANSAS

Delegate Count: 40 – winner take most

Voting hours on Election Day: 7:30am to 7:30pm

Early in-person voting?: Yes, 15 days before Election Day.

Open/Closed primary election?: Open. Voters can choose which party's ballot they wish to vote in. It does not register the voter with a particular political party.

Polling: There appears to be no readily available polling for the presidential primary between Trump and Haley in Arkansas. A poll from Echelon Insights in September 2023 put Trump 29 percentage points ahead of Florida Gov. Ron DeSantis, who was still in the primary race at the time.

Former United Nations Amb. Nikki Haley refused to drop out of the race after each defeat in the early primary contest states of Iowa, New Hampshire, Nevada and South Carolina. Super Tuesday is her last chance to prevent Trump from picking up enough delegates to sink her chances of an upset. Pictured: Haley speaks during a rally in Bloomington, Minnesota on Feb. 26, 2024

CALIFORNIA

Delegate Count: 169 – winner take most, unless a 50 percent threshold is reached, then it's winner take all.

Voting hours on Election Day: 7am to 8pm

Early in-person voting? Yes, 29 days before Election Day.

Open/Closed primary election?: California is a top two primary state, meaning all candidates are listed on the same ballot regardless of party affiliation.

Polling: Trump is 54.2 percentage points ahead of Haley in California (73.1 percent to 18.9 percent), according to FiveThirtyEight's average of the state's primary election surveys.

The largest blue state in the country, California has the most number of delegates to allocate in both the Republican and Democratic primary elections.

California's Republican Party changed its procedures this year that most view as a way to favor Trump.

If a candidate earns a 50 percent threshold in the primary election, they earn all of the delegates for the state.

Trump made remarks Monday from Mar-a-Lago after the Supreme Court ruled 9-0 against a Colorado decision that sought to remove the former president from the state's 2024 ballot

COLORADO

Delegate Count: 37 – winner take most

Voting hours on Election Day: 7am to 7pm

Early in-person voting?: Yes, 15 days before Election Day.

Open/Closed primary election?: Hybrid. If registered, voters must cast their ballot in their party's primary. But unaffiliated voters can vote for whichever ballot they choose in the primary – but only one.

Polling: There appears to be no readily available polling for the presidential primary between Trump and Haley in Colorado. There are several polls for a general matchup between Trump and Biden that put that president a handful of points ahead of his predecessor.

Colorado's Supreme Court ruled on December 19, 2023 that Trump is ineligible to appear on the state's primary ballot. The Justices claim that Trump violated Section 3 of the 14th Amendment by participating in an insurrection on January 6, 2021.

But the decision was appealed to the U.S. Supreme Court, putting a stay on the Colorado decision and allowing Trump to be included on printouts of the 2024 primary ballot in the state.

The Supreme Court ruled unanimously in a 9-0 decision on Monday – the day before Super Tuesday – that it was unconstitutional for a state to decide who can run for president.

While the High Court did not rule on whether Trump engaged in an insurrection on January 6, 2021, it did say only Congress can decide if Trump is, or is not, eligible to run.

The ruling by the 6-3 conservative panel paves the way to defunct lawsuits in other states – like Maine and Illinois – that are also trying to boot Trump from the ballot under the 14th Amendment.

MAINE

Delegate Count: 20 – winner take most

Voting hours on Election Day: 6am to 8pm

Early in-person voting?: Yes, as soon as absentee ballots are ready, which is usually 30-45 days before Election Day.

Open/Closed primary election?: Hybrid. If registered, voters must cast their ballot in their party's primary. But unaffiliated voters can vote in whichever party's primary they choose – but only one of them.

Polling: A February 15-19 poll by the University of New Hampshire Survey Center shows Trump 58 percentage points ahead of Haley in Maine (77 percent to 19 percent).

In Maine, Trump's name will appear on the ballot despite an attempt by Democratic Secretary of State Shenna Bellows to remove it.

She decided Trump should be removed under Section 3 of the 14th Amendment to the Constitution – the same argument Colorado used in its case. 

However, a Maine judge put that decision on hold pending the U.S. Supreme Court's decision on a similar case in Colorado. And now that the ruling has been handed down on the national level, Trump will remain on the ballot in Maine for the time being. 

Regardless, the ballots in Maine were already printed with Trump's name on them anyway. 

Bellows said: 'Donald Trump's name is in fact on the ballot, as are the names of all of the candidates who submitted petition papers, qualified and did not formally withdraw with the state of Maine.'

Activists unfurl a banner outside the U.S. Supreme Court in Washington d.c. as it heard arguments in an appeal of a Colorado case disqualifying Trump from the 2024 ballot under Clause 3 of the 14th Amendment alleging he 'engaged in insurrection' on Jan. 6, 2021. The Supreme Court ruled Monday in favor of Trump

MASSACHUSETTS

Delegate Count: 40 – winner takes most

Voting hours on Election Day: 7am to 8pm

Early in-person voting?: Yes, 10 days before primary Election Day.

Open/Closed primary election?: Hybrid. If registered, voters must cast their ballot in their party's primary. But unenrolled voters can choose which party's primary to take part in.

Polling: Trump is ahead of Haley by 36.2 percentage points in a FiveThirtyEight average of polling in Massachusetts. The latest taken February 3-6 by Advantage Inc./Fiscal Alliance Foundation has Trump with 65 percent to Haley's 22 percent – a 43 percent margin.

Massachusetts and Vermont are among the few states where Haley hopes she can pick up some more delegates on Super Tuesday.

As very blue New England states with either partially open or open primaries, more left-leaning and Democratic voters are able to head to the polls for the Republican primary to vote for Haley in protest of Trump's nomination.

MINNESOTA

Delegate Count: 39 – winner take all

Voting hours on Election Day: 7am to 8pm

Early in-person voting?: Yes, absentee voting 46 days before Election Day.

Open/Closed primary election?: Open. Voters can choose which party's primary they wish to vote in. It does not register the voter with a particular political party.

Polling: A survey conducted January 24-29 by SurveyUSA in Minnesota shows Trump 62 percentage points ahead of Haley (76 percent to 14 percent).

NORTH CAROLINA

Delegate Count: 74 – proportional

Voting hours on Election Day: 6:30am to 7:30pm

Early in-person voting?: Yes, third Thursday before Election Day.

Open/Closed primary election?: Partially closed. Each party can choose whether to allow unaffiliated voters to vote in their primary. This year, unaffiliated voters may choose which party's ballot to fill out. If none of the candidates earn 30 percent of the vote, there is a primary runoff for a few weeks after the election with the top two candidates.

Polling: Trump is ahead of Haley by 53.6 percent in North Carolina, according to a FiveThirtyEight polling average in the state. The latest poll from Capen Analytics on February 21 shows Trump with 64 percent and Haley with 36 percent in North Carolina – a 28-point margin.

Democrats are looking to flip North Carolina in the general election.

The state has a Democratic governor and attorney general, but a majority Republican legislature and is becoming increasingly purple over time.

In the 2016 presidential election, Trump won with 49.8 percent of the vote, which was 3.6 percent more than Hillary Clinton. That margin shrunk to just 1.3 percent in 2020 with Trump earning 49.9 percent to Biden's 48.6 percent.

The largest voting bloc in North Carolina is now unaffiliated voters, along with the number of registered Democrats going down and the registered Republican count going up. Democrats have lost 81,395 voters and Republicans have added 37,285 voters in the last two years.

Meanwhile, the number of unaffiliated voters in the state grew by 232,212 – meaning they can choose whether they wish to fill out a Republican or Democratic ballot.

The states breakdown is 36.7 percent unaffiliated, 32.5 percent registered Democrat and 30 percent registered Republican.

OKLAHOMA

Delegate Count: 43 – winner take most

Voting hours on Election Day: 7am to 7pm

Early in-person voting?: Yes, absentee voting the Wednesday preceding Election Day.

Open/Closed primary election? Partially closed. Each party can choose whether to allow unaffiliated voters to vote in their primary in November of each odd-numbered year. Since 2021, Democrats have allowed independents to vote in their primaries, but the Republican and Libertarian parties have not made the same determination. If a candidate does not earn 51 percent of the vote, Oklahoma holds a primary runoff a few weeks later.

Polling: A Morning Consult poll conducted in Oklahoma on January 23 through February 4 puts Trump a whopping 77 percentage points ahead of Haley (88 percent to 11 percent). Previous polling in the state put Trump up against DeSantis.

TENNESSEE

Polling: Trump is 69.9 percentage points ahead of Haley in the Lone Star State, according to FiveThirtyEight's polling average. The latest survey from YouGov taken February 2-12 shows Trump ahead by 71 points (80 percent to 9 percent).

Texas is the largest red state with the most delegates at stake in the primary election.

As the state bears the brunt of the southern border crisis, Texas voters are fired up this election cycle and want to get Trump back in the White House to reverse Biden's immigration policies.

Republicans say that immigration is their first issue when deciding who to vote for in the 2024 presidential election – followed by inflation and the economy. Independent voters list immigration as the second largest issue for them.

An NPR/PBS NewsHour/Marist poll taken earlier this month shows that 44 percent of Republican voters list immigration as their number-one voting issue.

The southern border crisis and illegal immigration remains the top issue for Republicans heading into the 2024 election. Pictured: A chain of migrants lock arms as they wade into the Rio Grande River to cross into Eagle Pass, Texas from Mexico on Feb. 24, 2024

Trump (pictured at the border in Jan. 2021) says that if elected president again he will initiate the largest deportation of illegal immigrants in U.S. history

WHAT ABOUT THE DEMOCRATS?

The Democratic presidential primary is still happening even though incumbent President Biden is the de facto nominee with essentially no serious contenders.

Rep. Dean Phillips (D-Minn.) is still running against Biden, but has so far failed to pick up a single delegate.

Democrats are holding Super Tuesday contests in the same states as Republicans with the exception of Alaska.

And the Democrats added Iowa to the list of states voting on March 5.

This year, Democrats broke from the decades-long tradition of holding their first contest in Iowa, while Republicans still had that state go first.
