A new Democratic Super PAC focused on winning back the House majority next year is set to launch its first paid media effort, targeting 10 House Republicans who backed Rep. Paul Ryan's (R-Wis.) budget plan.

In what it's calling a "substantial" media buy, the House Majority PAC is rolling out 60-second radio spots accusing Republican members of voting to "gut Medicare."

"Just days ago, Sean Duffy voted for the Republican budget plan that’s going to have the wealthiest Americans lining up at the trough," says one spot targeting freshman Rep. Sean Duffy (R-Wis.). "It protects billions in subsidies for big oil, and cuts taxes by trillions for the wealthiest Americans and big corporations. That’ll just make the deficit worse."

The 60-second radio spots begin Thursday and will run through next week. The group didn't offer a dollar amount on the buy, but those familiar say it's a six-figure effort. 

The nine other GOP targets are Reps. Paul Gosar (Ariz.), Rick Crawford (Ark.), Allen West (Fla.), Chip Cravaack (Minn.), Charlie Bass (N.H.), Ann Marie Buerkle (N.Y.), Joe Heck (Nev.), Francisco "Quico" Canseco (Texas) and Blake Farenthold (Texas).

The House Majority PAC's effort comes a day after the Democratic Congressional Campaign Committee rolled out radio ads targeting 25 House Republicans on the Ryan budget plan — an effort Republicans quickly slammed as minuscule. 

The conservative group American Crossroads highlighted the actual dollar amounts of the DCCC's radio buys district by district, which totaled around $5,000.
