Santorum’s ads in Iowa were even more negative than those of Romney; Santorum was actually the idea guy in the nasty campaign.
I think Santorum is prissy, spiteful, controlling and Bloombergish, his ideas are either non-existent, incoherent, or the same old same old big government, and I think he’s working hand in glove with Romney because he wants to be Romney’s VP.
Santorum lost his last election by 700,000 votes. That shows you what the good people of PA thought of him.
I would add that Santorum now trails Newt by ~440,000 votes through the first four states.
