The anti-tax Club is placing the 30-second spot with a suite of conservative outlets, including Breitbart and Fox News. It rolled out a first ad that criticizes Collins for voting for farm subsidies and federal budgets earlier this month.
The Washington-based organization is among several outside groups that are forcefully supporting Loeffler, who is facing a stiff challenge from Collins on her right flank and the Rev. Raphael Warnock, among other Democrats, on her left.
Tapped by Gov. Brian Kemp in December, Loeffler faces a November special election to fill the final two years of retired U.S. Sen. Johnny Isakson’s term.
