I wonder.
Isn't it more likely that there are more people like Kathleen, who hasn't posted here in a while, who are more likely to be like those who are last at the party and shocked when the lights are turned on and they're covered in puke and stale beer and that those people who looked so beautiful aren't?
You'd hope that the ones who went along with Trump believing it was the media and not Trump who was the despot/racist might be thinking twice about who they back.
Though there will be the jcpro's just like there are the dutch ovens, who will disappear and come back with a new name soon enough, there will also be those who will now claim they never backed Trump.
That 40% would be much harder to obtain again, unless Fox/NewsMax and social media double up on their messaging.
it's easy, though. Look at jcpro above. Right away finding a way to sneak Trumpism back in with a respectable coat of paint. It doesn't matter if it is incoherent - he literally says Trump ran on no foreign wars AND that a problem is that Biden will cut the military. "Peace through strength".
That core sentiment is over-represented in the primaries and as the base of the party. The Kathleens of the world mostly are fine with that as long as they can pretend the main people aren't as wantonly corrupt and anti-democracy as Trump was. The real problem is that the hard core base, which
wants those things, isn't going to go for a fake respectability. It is hard to thread the needle. That said, GOPers going over to the Dems aren't going to be as powerful there as they are in the current GOP. The incentive is to therefore just embrace the crazy. It may cost them in general elections, but look at how 2021 turned out. Losing big still left Trump very close to winning. A little more vote suppression and the GOP can overcome that, and even without it a good break puts them back in. The House is gerrymandered enough that they can always be competitive there without huge wins by the Dems. As long as the GOP is the "rural white man's party" they have a huge advantage in the Senate.
You are right that it may be they can't really win full power anymore this way. But that isn't certain, and until they lose consistently for a few cycles they won't change their approach. (And they will try just tweaking it slightly first.)
It took losing 5 out of 6 presidential elections by BIG margins for the Democrats to shift as far to the right as they did in the 90s. Except for Carter - who was pretty conservative and benefited from the country still being mad about Watergate - the Dems lost in 68, 72, 80, 84. without cracking 43% of the vote. They lost in 88 at the tail end of that with 45% of the vote. Losing by 8% was a good showing! It took that kind of beating for them to shift to their third way bullshit (and they overcorrected). It is going to take losing a lot more before the GOP gives up on Trumpism.
