Former Rep. Frank Guinta, R-N.H., who lost his seat in 2012 after one term, announced Monday he will seek a rematch with the Democrat who ousted him: Rep. Carol Shea-Porter.

After eyeing a comeback bid for months, Guinta made his decision official in a two-minute YouTube video, saying he is running again to work in a bipartisan way to reform government.

“As mayor of Manchester, I worked with Democrats and Republicans to improve the city,” Guinta says in the video. “Together we cut spending, lowered taxes and improved services. That’s the New Hampshire common sense we need in Washington.”

This will be the third time Guinta and Shea-Porter run against each another in the 1st District.

In 2010, Guinta defeated Shea-Porter by a 10-point margin. In 2012, Shea-Porter defeated Guinta in a rematch, 50 percent to 46 percent, which Republicans say was largely due to President Barack Obama’s get-out-the-vote operation in the state.

Without Obama on the ticket in 2014, Republicans argue Guinta will have a good shot of winning the seat back.

New Hampshire’s 1st District is rated a Tossup/Tilt Democrat contest by Rothenberg Political Report.
