The ads you describe sound like Willard's handiwork.
I’m pretty much in agreement there. Newt can’t even seem to compete in most states though, so I’m actually wondering why he’s refusing to face reality. Claiming the winning of your own state is a game changer, seems very desperate to me.
Granted, Santorum isn’t exactly burning up the primary circuit either, but he has surprised me.
I was thinking Willard or possibly even a SEIU effort here in California.
