Sen. Patrick J. Toomey is about to receive some extra air cover. 

Prosperity for Pennsylvania, a super PAC created specifically to help the Keystone State Republican’s re-election campaign, will begin running its first TV ad Friday in the Philadelphia media market. 

The 30-second spot, backed by a $1 million ad buy spread over two weeks on TV and digital, targets Democratic nominee Katie McGinty over taxes.

Washington Democrats support McGinty, the ad argues, because she wants to raise income, sales, and payroll taxes.

“Is there any tax she won’t look to raise?” the narrator asks. “Katie McGinty, more taxes for everyone.”

The ad features bobbleheads of McGinty, House Minority Leader Nancy Pelosi, and Senate Minority Leader Harry Reid.

Prosperity for Pennsylvania’s presence is a little unusual: Many Republican senators don’t have super PACs specifically tailored to their races, relying instead on the support of an outside group like the Senate Leadership Fund.

But the fund, which is connected to Senate Majority Leader Mitch McConnell, could struggle to raise money from certain wealthy donors who would otherwise give to Toomey, the former head of the anti-establishment, anti-tax group Club for Growth.  Prosperity for Pennsylvania provides those donors with an alternative avenue for their money. 

SLF and its non-profit arm, One Nation, have also combined to spend or reserve more than $10 million in ads in support of Toomey. 

Toomey and McGinty are locked in a tight race in this battleground state. The Rothenberg & Gonzales Political Report/Roll Call rates the contest a Tossup.
