House GOP campaign arm targets Dems on single-payer support

The House GOP's campaign arm is targeting Democrats over their support of a government-run health-care system, commonly referred to as single-payer.

In a new digital ad released Wednesday, the National Republican Congressional Committee instructs viewers to tell Democrats that "single-payer is not an option."

"As the problems with ObamaCare grow more severe, Democrats rally around another plan ... one more devastating than the last — single-payer health care," the ad begins. 

The ad features clips of prominent lawmakers like Sens. Bernie SandersBernard (Bernie) SandersOvernight Defense: Senate passes 0B defense bill | 3,000 US troops heading to Afghanistan | Two more Navy officials fired over ship collisions Senate passes 0B defense bill Dems fear lasting damage from Clinton-Sanders fight MORE (I-Vt.) and Elizabeth WarrenElizabeth Ann WarrenSenate Dems hold floor talk-a-thon against latest ObamaCare repeal bill Trump bets base will stick with him on immigration Dems call for action against Cassidy-Graham ObamaCare repeal MORE (D-Mass.) and House Minority Leader Nancy Pelosi (D-Calif.) talking about single-payer. 

Sanders will introduce his "Medicare for all" bill Wednesday with the support of one-third of Senate Democrats. 

The Democratic Party is far from united on single-payer, however. While it has 15 co-sponsors in the Senate, Pelosi and Senate Minority Leader Charles Schumer (D-N.Y.) have declined to endorse Sanders's bill. 

A similar bill in the House is supported by more than half of the Democratic Caucus.
