There’s a reason RFK Jr. has relatively high favorability and it isn’t that he’s about to win the nomination. https://www.washingtonpost.com/politics/2023/06/15/kennedy-desantis-polls-favorability/?itid=ap_philipbump
Apply skepticism to both Kennedy’s and DeSantis’s favorability ratings

« Favorability » is a tricky metric that depends on a few other things. Don't just take recent numbers for Robert F. Kennedy Jr. and Ron DeSantis at face value.

@pbump Have you heard any of RFK's family make any public statements of support?
@pbump yeah, his base is all anti-vaxxer wackos. He is a man without a home. He is a D only because of the family name, but even the nut job R’s who follow him would never vote for a Kennedy. They just like the chance to say “My best friend is … a Kennedy”.
