Or McCain/Romney?
"Romney also praised McCain for his general reform campaign when the Arizona senator came to Massachusetts to stump with Romney just before Romney's 2002 election victory in the governor's race. 'He has always stood for reform and change. And he's always fought the good battle, no matter what the odds,' Romney said at the time. 'Those are my values.'" (Eric Moskowitz, "Romney, McCain Spar On Campaign Finance," Concord Monitor, 4/27/07)
The bad hair/good hair ticket?
I doubt Romney would be content to play second fiddle to someone else, and McCain needs to reassure conservatives (given his track record on a number of issues), and there would be better choices to do that than a recent convert to conservativism (if he is a convert).
McCain would NEVER pick Romney. Lieberman.....Feingold.....he’ll go to a friend from his past.
