We aren’t in such a nice timeline.
I think it kind of depends on how he dies.
Massive ugly heart attack on live tv is different than someone shooting him in the head, and those are both different than like a bombing at one of his rallies.
It’d be a toss-up at that point, depending on who they put up before the election. Maybe Nikki Haley could actually win again Biden? The other non-candidates that ran during the primaries don’t seem like they’d fare well. That’d be hilarious if the party most opposed to women’s rights were to get the first female president in office. Losing Trump would be a speedbump for Conservatives though, they’re moving towards trying to take America down the road of a theocracy, I’m not sure that losing Trump would really stop that, they’re pretty much committed to making it happen at some point.
Liberals completely drop their guard and the republicans put someone up who is actually smart but still follows the far right agenda. Trump is chaotic (inept) evil at best, but the danger is getting lawful intelligent evil in.
I’m sure NYT and CNN would have a laundry list of reasons of why it was bad for Biden.
The truth is it would undermine the main reason to continue supporting Biden. That’s also why partisan democrats in Congress conveniently forgot about section 3 of the 14th amendment.
