Cheney is the reason many of us felt comfortable voting for Bush in 2000...he is a temperate and stabilizing force behind the throne, he isn't an egomaniac but a true patriot who has served his country for what, 3 decades? I still trust him, and the only way I would accept his leaving the ticket is if his health was obviously an issue. Then, I would replace him with...
Colin Powell!!!!
And make Cheney Sec of State
Sorry, but I think you'll find that Powell is going into retirement quite soon.
My sense is that if Cheney leaves that he will be gone and not step into a more stressful job..... jmo. Cheney deserves to be able to kick back and do what he wants now and I guess that could entail another cabinet job, but not my guess.
