Senate Majority PAC Defends Tester in First Statewide Ad in Montana

A Democratic super PAC is defending Montana Sen. Jon Tester from a recent attack by Americans for Prosperity with a TV ad of its own.

Senate Majority PAC, which supports Senate Democrats, is debuting its first statewide TV ad in Montana on Tuesday, backed by a $400,000 buy.

The ad responds to a $560,000 statewide TV and digital ad that Americans for Prosperity launched last week attacking Tester for not voting to dismantle the 2010 health care law. The message was a departure for the Koch brothers-supported group, which has focused on votes against last year’s tax overhaul in recent ads against other vulnerable Senate Democrats.
