I've said from day one that Guliani is overrated, and who would vote for Romney? Before being destroyed by his position on the war, McCain was the only candidate that seemed reasonably well-rounded - until Thompson entered.
If Iraq was to suddenly turn around, McCain might pull a comeback, but if I was betting it would be on Thompson. Hasn't the right been looking for another Reagan, anyway?
The entry of a well-rounded, seemingly moderate Thompson puts the pressure back on the Democrats. Will they risk fielding a woman or an African American? I'd vote for Obama over just about anyone, but would the nation?
