Why Biden should panic about Robert F. Kennedy Jr.: Daily Mail poll shows the independent is siphoning nine points from the president's 2020 vote while taking just four from Trump in a worrying sign for the Democrats

Independent presidential candidate Robert F. Kennedy Jr. is siphoning off 9 percent of voters who cast a ballot for Democratic President Joe Biden in 2020, exclusive new polling from DailyMail.com found. 

Overall, the March DailyMail.com/J.L. Partners national survey shows Biden trailing former President Donald Trump by four points - 39 percent to 43 percent - with Kennedy gobbling up 7 percent of the vote in the 2024 general election.

Among third-party candidates Kennedy has the most impact on the race, with Cornel West and Jill Stein receiving the support of 2 percent and 1 percent of the electorate, respectively. 

And he currently hurts Biden more, with only 5 percent of Trump's 2020 supporters flocking toward the prominent anti-vaxxer, allowing the presumptive Republican nominee to retain a lead over the current president. 

Of his 2020 voters, Biden only retains 73 percent, the DailyMail.com survey found. 

More of President Joe Biden's 2020 voters have moved over to independent candidate Robert F. Kennedy Jr. than those who supported former President Donald Trump four years ago the March DailyMail.com/J.L. Partners national survey found 

President Joe Biden is losing 9 percent of his 2020 voters to independent presidential candidate Robert F. Kennedy Jr., new exclusive polling from DailyMail.com shows, as well as 3 percent to Cornel West and 1 percent to Jill Stein. Another 4 percent head to Trump 

While 9 percent go to Kennedy, another 4 percent slide over to Trump. 

West, a civil rights leader who backed progressive Sen. Bernie Sanders in the 2020 race, takes 3 percent away from the incumbent president, while Stein, of the Green Party, gets 1 percent. 

The liberal Stein famously peeled away enough votes in Pennsylvania, Michigan and Wisconsin in 2016 to flip those three traditionally Democratic states to Trump during that election cycle over Democrat Hillary Clinton. 

Biden was able to flip all three states back to his column when he beat Trump in the 2020 race.  

As of now, Trump's 2020 coalition is less fractured, the DailyMail.com/J.L. Partners poll found. 

Of those who backed the Republican four years ago, 86 percent said they'd support him in his second reelection bid. 

Kennedy takes 5 percent of Trump's 2020 vote share, while Biden receives 1 percent.

Former President Donald Trump's 2020 coalition is holding together more than Biden's, with the ex-president retaining 86 percent of his vote. Still, Kennedy is gobbling up 5 percent, DailyMail.com's polling shows 

West polls at 0 percent, while Stein sucks away 2 percent of Trump's voters. 

'RFK Jr. matters because increasingly the signs are he is going to make it onto enough state ballots to be a genuine choice for voters,' said pollster James Johnson, co-founder of JL Partners. 'Even if he notches what he does in our poll – under 10 percent - that would be one of the best independent/third party performances in recent times.'

'At the moment RFK Jr is taking more votes from Biden than from Trump,' Johnson continued. 'He does particularly well amongst female voters, younger voters, and black voters – all demographics that Biden performs better amongst overall.'

J.L. Partners polled 1000 likely voters from March 20 to 24 via landline, cellphone, SMS and apps. 

The results carry a margin of error of +/- 3.1 percent. 

On Tuesday from Oakland, California, RFK Jr. announced that Nicole Shanahan would serve as his running mate. 

The 38-year-old Bay Area lawyer, technologist, entrepreneur and foundation head is the ex-wife of Google co-founder Sergey Brin - the 10th richest man in the world - and already put $4.5 million toward Kennedy's Super Bowl commercial.

The March DailyMail.com/J.L. Partners national survey shows Biden trailing Trump nationally by 4 points, with independent candidate Kennedy getting a 3 point bump since polling was conducted in December

She's expected to help fund the effort to get Kennedy or his affiliated We The People party on the ballot in states across the country. 

That's already been a challenge. 

In Nevada, for instance, the 15,000-plus signatures collected on behalf of Kennedy to get the independent on the general election ballot may be void due to the fact that he needed to have Shanahan named on his statement of candidacy. 

The Nevada Secretary of State's office admitted that the Kennedy campaign had been given bad information, though added the caveat that 'Nevada courts have been clear that the agency is not permitted to honor the employee's statements if following those statement would be in conflict with the law.' 

The Kennedy campaign did not buy that the attempts to throw out the signatures were a mistake, with Kennedy's callot access attorney Paul Rossi labeling the effort 'the epitome of corruption.' 

'After successfully collecting all of the signatures we need in Nevada, the DNC Goon Squad and their lackeys in the Nevada Secretary of State's office are outright inventing a new requirement for the petition with zero legal basis,' Rossi said.  

Kennedy's spokesperson confirmed to DailyMail.com Tuesday in Oakland that the campaign would sue the state to get the collected signatures to count.
