Nah, but he trolled the Republicans pretty hard by waiting until after their multi-million dollar convention where they badmouthed him for four days straight, only to drop out of the race and endorse vice-president Kamala Harris to run in his place, basically rendering most of the rhetoric over the week pointless.
Also with how much centrists seem to like Kamala, the GOP decision to nominate JD Vance for VP is looking increasingly unwise as instead of going for a centrist to balance out Annoying Orange's right-wing extremism like they did with Mike Pence, Vance is more right-wing extremist than even Annoying Orange, and them doubling down on that has already shown to cost them support from the centrist Republicans.
Make no mistake, this is still a clusterforget, and waiting so long to drop out has definitely thrown more than a little confusion into the upcoming democratic convention as everyone who voted for Biden in the primary is going to essentially be disregaurded as the demcocrat district delegates cast their ballots on who will be the presidential nominee without input from voters during the primary election for the first time since 1972, and there is no time to organize a second primary election, especially in conservative states which will go out of their way to block staging additional elections.
