A Democrat-aligned super PAC is coming to the defense of North Carolina Sen. Kay Hagan, who was hit last week in a TV ad from a conservative outside group.

Senate Majority PAC launched a TV ad today that attempts to debunk the attack ad from Americans for Prosperity, which slammed the Democrat over her support for the health care law. The new spot, backed by a $400,000 buy, also highlights Hagan’s record, calling her an “independent senator working to help balance budgets and create jobs.”

There is a crowded Republican primary to take on Hagan in the general. The race is rated Tossup/Tilt Democrat by Rothenberg Political Report/Roll Call.
