Let the health care (civil) wars begin.
The American Action Network, a center-right nonprofit group affiliated with establishment GOP House leaders, is running ads targeting Republicans who don't support the bill to repeal and replace Obamacare.
Several hard-line Republicans have blasted the "American Health Care Plan" this week, dubbing it "Obamacare 2.0" and "Obamacare lite."
The group spent $500,000 on the ads, which will air over the next two weeks on Fox News and in 30 different congressional districts nationwide.
The ads urge lawmakers -- including House Freedom Caucus Chairman Rep. Mark Meadows (NC), Rep. Mark Sanford (SC), Rep. Louie Gohmert (TX), Rep. Dave Brat (VA) and Rep. Justin Amash (MI) -- to "vote with President Trump" and support the House health care bill.

Amash didn't seem worried about "the Establishment" spending money on the ads.
Many people thanked Amash and other lawmakers on Twitter for sticking to their guns.
Others said the rebels should get in line with Trump's plan.
According to its website, the American Action Network is a 501(c)(4) 'action tank' that supports center-right public policies.
It was established in 2010 by Fred Malek, who worked with Presidents Nixon and George H.W. Bush and former Rep. Norm Coleman (MN).
American Action Network officials also run the Congressional Leadership Fund Super PAC, which works to elect a Republican majority in the House.
On Monday, members of the House Freedom Caucus and several Senators, including Rand Paul (R-KY), spoke out against the House health care plan and announced they would introduce their own bill to fully repeal Obamacare.
Trump has said he supports the House plan and is deploying Vice President Pence to travel across the country in the coming weeks to champion the bill.
Trump hinted on Twitter that Republican rebels would soon "come along" to the plan.
