Bill Clinton Backs Tammy Baldwin In New Wisconsin Senate Ad

Rep. Tammy Baldwin (D-Wis.) is out with a new ad featuring former President Bill Clinton, as she works in the final week to defeat Republican Tommy Thompson for the state's open U.S. Senate seat.

The ad hammers home one of Baldwin's main campaign messages -- that she will fight special interests -- and undercuts the far-left extremist label Thompson has been trying to pin on her.

"One big difference between Tammy Baldwin and Tommy Thompson is that she stood up to the special interests, and he stood up for them," says Clinton in the ad. "If you put people first, it works better than trickle-down economics. Thanks to Tammy Baldwin, there are 3 million young people under the age of 26 who are now on their parents' health insurance policy. We will bring America back in a fair, balanced, progressive way, with Tammy Baldwin. You can count on it."

Watch:

The Senate race in Wisconsin has been extremely tight and negative. It has also been the most expensive in state history.
