They aren't hard to find. You know about this ad because it's the first one Santorum has run, and the liberal media wants to let the world know, hopefully to keep conservatives split to help Romney. I see it is working for them, not that it's that hard to split conservatives these days.
Thanks. That answers my question, although that ad came out in mid-January.
Seems to me that he'd be running that ad, instead of the new one attacking Newt, if he really means to fight for our cause.
It's a good ad - right up until the end, when they show Rick at a campaign rally. The man looks stressed out and unhappy. Not like a winner at all. Very uninspiring. A little unsettling, even.
