This one is not going to happen, but it was suggested to me as a possibility. It is…

McCain/Giuliani is the GOP ticket in 2008.

McCain will be 76 in 2012, so he’ll step aside and let Rudy carry it that year and in 2016

All things being equal, the ticket would be formidable; the Republicans would first have to realize, though, that the complexion of their party would be forever changed.

(Just kicking things around…)
