FYI on the effect of RFK dropping out, here is what FiveThirtyEight's model says.

Might matter in an election this close, but people probably are overstating it.

The other third party candidates are more relevant to damaging Harris' chances. But they have ballot access issues that might attenuate their effect.

RFK's voters in polling are generally low engagement voters, so they might stay home if he isn't in the race.

Of course let's stay tuned to see if he endorses Trump.
