I think you guys are way underestimating what will happen when Trump dies. This is not some coalition of the willing...the GOP is full MAGA and that wont die with Trump no matter how much you wish on falling stars and throw pennies into fountains. There was a reason Vance got the nom and it is that he is friendly with the people who have the one thing the GOP (and half the Dems care about) money. Untapped billions. Oh and he fully doesn't care about the voters so he won't even pretend to not support Project 2025 and will open every lane possible to let it happen.
The knives aren't going to come out because they will be paid to put them away. (plus there is no non-MAGA GOP left...those with knives were kicked out) You think Trump is handled with kid gloves...watch what the media does to Vance and his Tech Bro Alliance. He will be heralded as young and innovative, progressive thanks to his non-White wife and the outsider Trump couldn't be in term 2 since Vance is still rather new to politics. The Dems will completely back off of him because he doesn't have the vitriol Trump does and since he was a Senator they think they can work with him. No one will do anything of value for fear of upsetting the billionaire class. Especially corporate media who is owned (or wants to be) by many of these people.
Trump cares about his legacy Vance does not. Vance will burn it all and hide behind his fake smiles and Ozempic Induced look of youth and health. He will gaslight people into believing he didn't agree with the Trump stuff they hate, the media will let him, and then he will dial it up to 11 because he knows he has one shot at this. Vance may have rolled a 1 on charisma, but he aint just going to shrink away because he struggles having conversations. Hell I bet ABC and CNN will pretend it is cause he is Autistic and then use that to prop him up as well. He is going to be given every chance to succeed and even if he doesn't half of Washington will be paid handsomely to pretend he did.
