And if Palin dies before McCain? Or if Obama dies and you get Biden?
Seriously, everyone makes it sound like McCain is going to die, statistically he isn't.

You are right, Cheney is really a Deputy President not VP and he goes waaay beyond his authority, but so does Bush.
I really think they should both be impeached for going against their oath to defend the constitution. Good intentions (at best) are not enough to let your break the rules.
