If McCain doesn't get on the ticket in 2008, I doubt there is any chance he'll ever run again. He was born in 1936 so he would be 72 in 2008. Bob Dole was 73 when he ran in 1996. Ronald Reagan was 73 when he ran for his second term in 1984. If elected in 2008, McCain would be the oldest candidate ever elected president for a first term. If he had to wait till 2012 to get the Republican nomination, he would be the oldest presidential candidate in US History. Pretty unlikely.
McCain, McCain, McCain, You're making me break out in hives.
Let's speculate about Rove getting on board with any new candidate.
Calamine for my itch.
