Less than two weeks after launching his first television ads, Democratic congressional candidate Raul Ruiz released another commercial.

The ad, which started airing Thursday, features the emergency room physician in a hospital discussing the partisan gridlock that has stalled many efforts in Congress.

The ad never mentions his opponent, Republican Rep. Mary Bono Mack of Palm Springs.

But it does end with a fist bump that is reminiscent of the one President Obama and First Lady Michelle Obama famously did on stage.

Ruiz’s campaign said the ad buy was “substantial” but didn’t provide additional details.

Bono Mack’s camp hasn’t responded to the ad yet. But a super PAC that launched this year in support of her re-election bid did.

Californians for a Stronger America launched its first television ad this morning, which features unflattering photos of Ruiz points out that he has been supported by Minority House Leader Nancy Pelosi.

The ad wraps by saying Ruiz will be a “Pelosi puppet in Congress.”

Political action committees are not allowed to coordinate their messages with the candidates.

But that didn’t stop Ruiz from blaming Bono Mack for the ad today.

“It says a lot about how much Congresswoman Bono Mack has changed that her first ads come from an anonymous, out-of-state committee, run by a man once labeled a ‘henchman’ and ‘political hack’ by the New York Daily News,” Ruiz said in a statement.

“The old Mary Bono Mack never would have let this happen. Washington has changed her. Mary Bono Mack has become just another hyper-partisan career politician who cares more about her political career than doing what’s right.”

Bono Mack’s own campaign has released both television and online-only ads this cycle. But her TV spots were targeted to the primary election, not the Nov. 6 vote.
