I've also found this to be the case. They are like zombies lol
Zombies is right, but zombies or not, that's a big part of Bush's constituency, and he has to figure out a way to lead them. Love FDR or hate FDR, he managed to provide leadership, in a difficult time, beyond his political base. Same for Reagan. Cheney is in the way because people just plain don't like Mr. Burns and that's something that nothing whatsoever is going to change. Bush has to wipe away all suspicion that he is in fact Smithers.
