I doubt Vance is capable of getting the support from Congress and the maga voters that Trump has. Once Trump is gone, the Republican party is going to have a hard time putting itself back together.
Meanwhile, the individual upthread suggesting they’d support a foreign power invading the US and capturing Trump is the ridiculous, childish, and deeply unserious brand of self-loathing that we are voraciously (and necessarily, if our country is to survive) opposed to.
You, personally, might, but I think it's going to be a clusterfuck. You can't stick a different person in a cult of personality and expect it to act the same.
