To YOUR point... I'm just not sure that will end up being enough, to get enough non MAGAs, and non Progressives, to pick Trump. I guess what could decide it...who gets more "hold your nose" votes?
My view on it...the sooner Trump is out of politics, the sooner the GOP can back fill with some more reasonable leadership. And when/if that happens, that will put pressure on the Dems to push their farther right members, further out of leadership roles.
Biden and Harris are only still relevant because of Trump. One could argue that Trump only became a thing because of the pendulum shift to more progressive leadership in Washington...that's a very valid argument. But I think Trumps unique personality, presence, and some of the nerve threads he strikes, have A LOT more to do with the MAGA phenomenon...
The unfortunate side effect, for the country and not just for the GOP, is he is eroding many of the great pillars that the GOP has stood for for years...MAGA is strong, its a very large and obviously loyal voting segment...everything outside MAGA though...slow erosion. And that erosion is singularly because of Trump, and its like protein for the progressive movement right now.
