Rep. Phil Gingrey, R-Ga., has debuted a new ad making fun of a spot from his Senate primary foe, businessman David Perdue, that portrays members of Congress as a pack of crying babies.  

In Perdue’s ad , four crying babies wear shirts bearing the names of his four major opponents in the Senate race.  

Gingrey, an OB-GYN, begins his own ad with a clip of Perdue’s ad, showing a baby meant to represent Rep. Jack Kingston, R-Ga., and a baby meant to represent Karen Handel, the former Georgia secretary of State.  

In the spot, Gingrey dismisses the spot as too “clever” by half.  

“You deserve better than politics as usual,” he says, speaking to the camera. “Having delivered over 5,200 babies, I understand, when it’s time, it’s time. And the time to stop Obama is now.”

The campaign has put $275,000 behind the ad, which will run in the Atlanta, Macon, Columbus and Augusta markets for one to two weeks.  

Recent polls have shown Gingrey trailing Perdue, Kingston, and Handel. GOP Rep. Paul Broun also trails in polls.  

The Senate seat is open because Sen. Saxby Chambliss, R-Ga., is retiring.  

The primary is May 20. If no candidate receives a majority of the vote — likely given the crowded field — the race will likely continue in a runoff later this summer.  

The Republican nominee will face Democrat Michelle Nunn.  

The race is rated Favored Republican by the Rothenberg Political Report/Roll Call.
