The National Republican Congressional Committee (NRCC) is pushing House Democrats to commit to focus their campaigns on ObamaCare with a new tongue-in-cheek petition.

The NRCC is targeting vulnerable incumbents and candidates in a few dozen districts demanding that they promise to stand up for the law, which polling shows is fairly unpopular after its rocky rollout.

"I have been a strong and consistent supporter of ObamaCare," the petition begins. "The law may be incredibly unpopular as people in my district are kicked off their health care plans and watch as their premiums and costs skyrocket, but I still support this law — and commit that I will continue to support it through Election Day." 

The petition cites promises from House Minority Leader Nancy Pelosi (D-Calif.) and Democratic National Committee Chairwoman Debbie Wasserman Schultz (D-Fla.) that their members will run on the controversial law. While Democratic leaders have insisted their rank-and-file members will run on the law in 2014, some Democrats have sought distance from parts of the law.

Republicans believe ObamaCare will be an albatross around Democrats' necks in 2014, and this is the latest sign the GOP plans to target the law as a top campaign issue this year.
