Trump and Biden set to formally clinch Republican and Democrat nominations today as states including Georgia, Mississippi and Washington go to the polls for primaries

Donald Trump and President Joe Biden are both expected on Tuesday to reach the number of delegates needed to win their respective primaries and solidify a rematch in November.

Georgia, Mississippi and Washington state are holding both Republican and Democratic primary contests on Tuesday – while Hawaii will hold its Republican caucuses and Democrats abroad and living in the Northern Mariana Islands will head to the polls.

Before Tuesday's results, Trump holds 1,078 delegates and needs 1,215 to be nominated by the GOP in July. Biden ⁦has 1,866 delegates and needs 1,968 for the Democratic Party's nomination.

Both parties hold their nominating conventions over the summer where delegates will convene and the candidates will officially be announced and the ballot set for 2024.

Voters heading to the polls on Tuesday will most likely give the final delegates needed for Biden and Trump to reach their respective thresholds and the rest of the states' primary elections won't make much difference after that.

The results Tuesday are likely to solidify a 2020 rematch between former President Donald Trump (left) and President Joe Biden (right) in November 

Americans have made clear in poll after poll that the majority don't want a rematch of 2020 this year, but primaries played out to the contrary despite voters being presented different options – especially in the Republican contest.

There were at the height more than a dozen others opting to take Trump's spot as the GOP nominee this November, but none were successful. Biden, as the incumbent, had less challengers but still faced bids from Rep. Dean Phillips, self-help guru Marianne Williamson and Robert F. Kennedy Jr. – who is now running as an independent.

Trump swept all four early primary states of Iowa, New Hampshire, Nevada and South Carolina earlier this year. He also took 14 of the 15 states that voted last Tuesday.

After Super Tuesday last week Trump's remaining competitor Nikki Haley finally suspended her campaign, but did not endorse her rival and instead urged him to 'earn' the votes of her supporters.

Of the states voting on Tuesday, the results in Georgia are perhaps the most consequential.

To highlight this, Biden and Trump held dueling campaign events in Georgia on Saturday. Trump rallied in Rome, Georgia with Rep. Marjorie Taylor Greene and Biden held a campaign event in Atlanta just an hour earlier.

Georgia is one of the most important and consequential states in 2024. Trump lost to Biden by less than 12,000 votes in the 2020 presidential election

Trump lost to Biden in 2020 by less than 12,000 votes – or 0.3 percent – in Georgia. The Peach State has become the center of controversy after allegations Trump made a call after the election telling Georgia Secretary of State Brad Raffensperger to 'find' the votes needed for him to clinch a victory.

The former president and his allies claim Georgia was rich with election fraud in 2020. Meanwhile, Trump is facing a lawsuit in Fulton County brought by District Attorney Fani Willis for his election fraud claims.

As a key swing state, Georgia will be closely watched in 2024 and is one of the states that could determine who will be president next year.

Georgia has 108 Democratic delegates to dole out and 59 for Republicans – and 16 Electoral College votes for the general election this year in accordance with the 2020 census.

Meanwhile, Mississippi has 35 Democratic and 40 Republican delegates in the primary and Washington has 92 Democratic and 43 Republican delegates.

Lara Trump, wife of former President Trump's second son Eric, was elected co-chair of the Republican National Committee (RNC) on Friday.

She said Sunday that the RNC will become laser focused on prosecuting 'election cheaters.'

'I can guarantee you, that over the next 8 months, you are going to see things happen at the Republican National Committee unlike you have ever seen before. Because this is a must win election!' Lara told Fox News host Maria Bartiromo.

She told Bartiromo just two days after becoming co-chair that they are working to establish a network of volunteer poll watchers in 2024 and lawyers amid 78 lawsuits in 23 states where the RNC is trying to make it easier to vote and 'harder to cheat.'

Former President Trump's daughter-in-law Lara Trump unanimously won the election to become the Republican National Committee (RNC) new co-chair during the spring meeting in Houston, Texas on Friday

'We have to ensure that when people go vote they feel like their vote counts, that they are inspired to go vote. We can never allow what happened in 2020 and the questions surrounding that election to ever happen again,' she said.

'So I'll tell you right now what is already under way at the RNC,' Lara continued. 'We have for the first time ever an 'Election Integrity Division' – this means vast resources dedicated solely to this cause.'

She made it clear that the main goal of the RNC will now be to attack those who think 2020 was legitimate and to launch litigation against those who they believe are trying to 'cheat' or interfere unlawfully in the 2024 election.

'I want to say to anyone out there who's thinking about cheating in an election, we will go after you,' the new RNC co-chair warned. 'You will be prosecuted to the full extent of the law. It is not worth it.'

'Every person in this country, Maria, whether you are a Republican or a Democrat, should want free, fair, and transparent elections.'
