The conservative group Americans for Prosperity is going up with ads in several House districts highlighting the glitches on the Obama adminstration's new health-care exchanges Web site.

The ads thank Reps. Steve Southerland (R-Fla.) and Mike Coffman (R-Colo.) for opposing the health-care law, known as the Affordable Care Act and Obamacare, and attack Reps. Ron Barber (D-Ariz.) and Scott Peters (D-Calif.) for declining to oppose it.
