It's why they're moving so quickly to destroy the government; they know they only have until he dies to pull it off. The goal is to fuck everything up so royally in the time they have that it can't be fixed. And they may have been successful; that remains to be seen.
But the MURRICA FUCK YEAH folks aren't going to fall in behind Vance. The best he can manage is marshaling the crypto brunchlords.
The fact is, they don't have a single person with his charisma, and when he's gone, unless they've enacted IRON control over what's left of the government, it's all going to fall apart.
I hold a different opinion. I hope *yours* is the correct one. :)
