Since Friday morning, the Romney campaign has been beaming an unusual 30-second spot into media markets across the state of Florida. It consists almost exclusively of a vintage video clip from Jan. 21, 1997, the day Newt Gingrich was sanctioned by his House colleagues after an ethics investigation.

What makes the ad striking is the content:  NBC Nightly News anchor (at the time) Tom Brokaw, is introducing his network's report that evening on Newt's downfall earlier in the day.  That's all there is, and the video bite is perfectly sized for a political ad.
