This Weekend in Presidential Campaign Ads

Lots of ads, very little negativity over the pre-Thanksgiving weekend:

Mike Huckabee's first ad doesn't have much money behind it, but it does star Chuck Norris.

The latest by Hillary Clinton enlists an old friend, first seen in one of her Senate ads, to send a message about trust.

Barack Obama's new spot is aimed at workers and the middle class.

Romney delivers a familiar family-values theme to both Iowa and New Hampshire.

And Joe Biden proves everyone thinks he's always right in a new web video.
