McCain is too stupid to select someone like Romney. Look for McCain to select someone like Jack Kemp, Lindsay Graham or Joe Lieberman. McCain is a “slow leak”.
To be honest, I hope Mitt would turn McCain down for the VP slot and that Mitt would continue meeting regular Republicans across America and just become more well known in Conservative circles.
Let McCain pick Joe Liebermann and have a go at a Centrist Coallition trying to win the election, Conservatives or people who hold those views really do not need to mix up with John McCain, if he loses (and he may not) whomever is with him will be tarred with the loss ala Dan Quayle.
