Turns out he overestimated his appeal among people capable of basic reasoning skills, so since he's realized he's actually siphoning mostly Trump voters it's time to pull the ripcord on the plan.
Lots of people didn't want trump or Biden, but were still going to vote for down ballot races.
The presense of literally anyone not named trump or Biden on the ballot would have gotten votes from Biden. Most people won't leave a race blank on the ballot and wouldn't bother a write in, they'd just pick any third option.
But Kamala is bland enough, no one has that objection to voting for her when they normally vote D.
Unless she royally fucks something up, that won't change before the election.
I'd imagine because of that, RFK Jrs donations have dried up from Republicans wanting to stop Biden. There's no monetary incentive now, he never had a chance of winning, and all he's doing is destroying the Kennedy name.
So he's not directly doing it because he can no longer help trump, but the reasons he's dropping out circle back to Biden dropping out.
I don't think RFK jr is cognizant enough to even realize all that. He probably thinks people stopped donating because the media was mean to him
Nah, he has been negotiating with Trump and Harris to see if he could get a cabinet seat. Trump probably said yes and RFK is going to bow out of the election and endorse Trump.
