Robert F. Kennedy Jr.'s sister Rory reveals she WON'T vote for him in 2024... but insists she still loves him and reveals why it has nothing to do with his views

Rory Kennedy, the sister of independent presidential candidate Robert F. Kennedy Jr., said Monday that she fears former President Donald Trump being elected so much that she won't cast a ballot for her own brother. 

She said in an interview with NBC's Andrea Mitchell that a second term for Trump 'will be catastrophic, honestly, for not just our country, but for the world.' 

Kennedy - who was promoting her latest documentary series, The Synanon Fix -  was among the group of family members who went to St. Patrick's Day festivities at the White House and posed for a group photo with President Joe Biden in a show of support. 

'You know, the truth is, that I love my brother, and it pains me to come out against him, but I am very concerned with the stakes in this election, and I'm very concerned from the polls I'm seeing that he takes many more votes from Biden than he does from Trump,' the documentary filmmaker said. 

'And I think this election is going to come down to a handful of votes in a handful of states, and I'm concerned that his campaign and running for office as an independent is going to lead to Trump's election,' she added.

RFK Jr. launched his campaign in April and said he would run against Biden in the Democratic primaries but when he didn't gain enough traction to best the president he announced in October that he would run as an independent in the general election instead.

His sister told Mitchell, 'I'm a huge fan of President Biden's.'

'I think he’s done fantastic job and doesn't quite get the credit he deserves over the last four years in terms of policies that he’s enacted and changes that he’s made that I think have been enormously impactful and positive,' she said. 

Still, Biden is trailing Trump in the polls.  

The March DailyMail.com/J.L. Partners national survey shows Biden trailing Trump by four points - 39 percent to 43 percent - with RFK Jr. gobbling up 7 percent of the vote in the 2024 general election.

RFK Jr. currently hurts Biden more, siphoning off 9 percent of voters who cast ballots for the president in 2020, whereas only 5 percent of Trump's supporters four years ago say they'll choose the independent candidate. 

Ipsos polling is more favorable to Biden, with RFK Jr. peeling supporters from the Democrat and Trump about evenly and longterm could be more damaging to the ex-president because of the kind of voter the independent is attracting - the 'disaffected suburban moderate Republican,' Ipsos President Cliff Young told DailyMail.com last week. 

Still, all signs point to the 2024 race being incredibly close between the major party candidates. 

'So I feel that the stakes couldn't be higher, frankly,' Kennedy told Mitchell. 'So, you know, I would love more than anything to sit out on the sideslines on this one and not be in this position, but I don't feel like I can do that.' 

On Tuesday, RFK Jr. announced that his running mate would be Bay Area lawyer and entrepreneur Nicole Shanahan, 38, who is new to politics but not the spotlight - as she was previously married to Google co-founder Sergey Brin.

She denies a salacious Wall Street Journal report that said a tryst with Elon Musk broke up her marriage with Brin and killed the two billionaires' friendship. 

As Shanahan begins appearing with RFK Jr. on the campaign trail, the campaign continues to work to gain access to general election ballots across the country.

On Monday RFK Jr.'s campaign announced they had enough signatures to get on the ballot in North Carolina, which could end up being a swing state due to the governor's race. 

Last week the Kennedy campaign went to war with Nevada after finding out that the signatures already gathered may not count because Shanahan's name wasn't included on the petition for candidacy. 

The Nevada Secretary of State's Office admitted that the campaign had been given bad information. 

A spokesperson for RFK Jr. told DailyMail.com that the campaign plans to sue the state to make sure the signatures gathered will count.
