KNOXVILLE, Tenn. -- With the limited amount of time spent in my hotel room, only a dozen or so ads have been delivered to my aural/audio sensors. The ad I've seen the most: This one from Restore Our Future. The final, sit-down CNN debate has been mined like North Dakota shale.

The ad I've seen only a little less often: Real People, brought to you by the pro-Newt Winning Our Future, explaining why they can't relate to a snobby guy who probably doesn't even pump his own gas.

The ad I've seen the least, just twice: This stark, minimalist Santorum commercial, paid for by the campaign itself.
