Democratic Sen. Russ Feingold of Wisconsin is the target of a television ad campaign pressuring him to demand that the public insurance option be included in the final health care package.

Feingold, who is running for re-election in 2010, strongly supports the public option. He voted for the Senate version of health care overhaul legislation even though a public option was dropped from the $871 billion package to secure the support of moderate Democrats.

The small, $20,000 buy is set to run through the weekend on Wisconsin broadcast television in the Madison, Milwaukee and Green Bay markets. The 30-second spot features video clips of President Obama explaining why he is a proponent of the public insurance option. At the end of the ad, a recommendation appears: “Tell Russ Feingold: A bill without a public option is not change we can believe in.”

The ad is the product of Progressive Change Campaign Committee, and is being run in concert with a robo-call campaign that also focuses on Feingold.
