Romney's presence would emphasize too many of McCain's weakness, from major ones, such as ignorance about economy and adultery, to trivial ones but allegedly important to some voters such as hair and height (McCain is barely 5'6”).

McCain is a culturalist, somewhat like Pat Buchanan. I can't see he picking someone like Romney.
