Slight correction: RFK Jr didn't withdraw. Here's what he said:

"I also want you to know that I am only suspending my campaign, not terminating it. My name will still be on the ballot in most states. If you live in a blue state, you can vote for me without harming or helping President Trump or Vice President Harris. In red states — the same applies. I encourage you to do so. And IF ENOUGH OF YOU VOTE FOR ME AND NEITHER OF THE MAJOR PARTY CANDIDATES WIN 270 ELECTORAL VOTES, I COULD STILL WIND UP IN THE WHITE HOUSES in a contingent election." (capitalized emphasis mine).
