The conservative group Americans for Prosperity released new round of television ads Thursday targeting a pair of House Democrats over the federal health-care law.

The commercials target Reps. Ann McLane Kuster (D-N.H.) and Rick Nolan (D-Minn.), who each face potentially tough reelection campaigns. And they offer an early signal of how Republicans plan to tie congressional Democrats who were not around to vote for the health-care law to the issues that have plagued its implementation this year. Neither Democrat was in Congress when the law passed in 2010.
