"Facing a loss at a 2008 straw poll event this weekend, Senator John McCain of Arizona told his supporters to write in President Bush [?] as a sign of support, leaving many sputtering."

I don't think he has much to fear from Frist, so why pull such a sill and transparent stunt? Why not just say "I think it's too early to be campaigning for 2008" and let it go?
