I'd like to believe that, I really would, but let's be honest with ourselves. The current republicans (in leadership) aren't stupid. They've gotten pretty decent at running with donald's bullshit and spinning it. They also know that politics isn't much different than sports teams for the vast majority of the voting public in america. They'll not have trouble finding someone who is charismatic enough to spit verbal acid at opponents in a primary AND can be riled up against the demographic target of choice.
The only real challenge for them will be 1.) finding someone with donald's 'blessing' or a connection to him to set it up as 'taking over' so the republican voters will find it so amazing, AND 2.) ensuring someone like musk doesn't try to torpedo everything by using vast amounts of money to try to buy their way into the ring.
Didn't 'the youth' break for trump in historic proportions compared to previous elections? The males, at the very least.
