The Democratic Congressional Campaign Committee has launched a round of robocalls targeting 13 Republicans. The calls, according to a sample script released by the DCCC, hammer away at Democrats’ message of criticizing the GOP’s budget plan to dramatically overhaul Medicare.

The calls hit Members for voting in favor of Budget Chairman Paul Ryan’s (R-Wis.) budget blueprint, noting the GOP’s “plan to end Medicare actually increases the debt by almost $2 trillion because of more tax breaks for millionaires and corporations.”

Democrats believe their Medicare messaging was a key component of their win in New York’s 26th Congressional district, where now-Rep. Kathy Hochul beat Republican Jane Corwin.

The calls target Republican Reps. Ben Quayle (Ariz.), Daniel Webster (Fla.), Steve King (Iowa), Bobby Schilling (Ill.), Charles Bass (N.H.), Jon Runyan (N.J.), Joe Heck (Nev.), Nan Hayworth (N.Y.), Ann Marie Buerkle (N.Y.), Steve Chabot (Ohio), Lou Barletta (Pa.), Kristi Noem (S.D.) and Scott Rigell (Va.).
