Well, there is an upside. Mitt is pretty thin-skinned. Perhaps the Obama negative attack will inspire Mitt to fight back and attack Obama in return.
I don’t think Romney can win if he just tries to maintain the “nice guy high road” approach that cost McCain the 2008 election.
Seconded. If Romney's going to make a run at winning this thing, he has to go on the offensive and pound Obama to death where he's weak. He should use the Clintonian "It's all about the economy" concept to full effect.
He needs to show some genuine humanity, too. Somehow, he has to show some depth; that he's not a Guy Smiley car salesman type.
