Rep. Todd Tiahrt (R) hit the Kansas TV airwaves this week with the first spot in his Senate primary campaign against Rep. Jerry Moran (R).

Tiahrt blasts the federal stimulus plan in the spot, criticizing Speaker Nancy Pelosi (D-Calif.) and President Barack Obama for contributing to further economic decline.

“But one Kansas conservative, Todd Tiahrt, said the bailouts and stimulus were wrong from the start,— an announcer says in the ad. “Now Tiahrt’s fighting to stop it. Go to his Web site. Help Todd Tiahrt stop Obama and Pelosi now.—

A spokesman for the campaign, Chuck Knapp, would not disclose the size of the ad buy. A release from the campaign said Tiahrt has introduced legislation that would repeal the stimulus package.

Moran also voted against the stimulus bill that passed through the House in January.
