ForAmerica, a conservative non-profit headed by L. Brent Bozell III, the founder of the Media Research Center and Parents Television Council, has launched a new attack video against Republican Sens. Lisa Murkowski, Shelley Moore Capito, and Rob Portman over their refusal to support a repeal-only bill for the Affordable Care Act.

Pretty, pretty good: The video — now in the Facebook feeds of the nearly 8 million people who have liked ForAmerica — shows the senators arguing for a clean repeal of the ACA in 2015 as the theme music from Curb Your Enthusiasm plays in the background.

Why it matters: The video shows that Republicans are willing to break ranks and attack their own to repeal the ACA, potentially widening fault lines in the GOP over the contentious issue.
