What's Wrong with Mitt Romney?

On Ross Douthat's blog today I read that Mitt Romney is the least popular of candidates with the Republican Party. This struck both me and my father as odd. He is the most mainstream Republican in the race. He is not a populist like Huckabee; he is not a pro-choicer like Giuliani; he is not lazy like Fred Thompson. The problem with him must be, then, that, as Frank Rich has pointed out, he is a follower, not a leader. Even though he wears a charismatic exterior, there is nothing new about him. He may be a perfect person to work with, but, in spite of what Governor Huckabee said, he is not the right guy to lay people off.
