“Sure. There’s plenty we agree on,” said Senate Majority Whip John Cornyn (R-Texas) late Wednesday when asked whether he can get 50 votes. One challenge for GOP leaders is “trying to explain the concept that we need to do it this way, as opposed to solving all the problems in a Senate bill now.”

Cornyn said broader negotiations on Medicaid reforms and other divisive issues would likely re-emerge in bicameral negotiations with the House. But some Republicans are worried that those talks would revive efforts to wind down a Medicaid expansion that’s benefited their states.

Centrist GOP Sens. Rob Portman of Ohio and Shelley Moore Capito of West Virginia were undecided on the so-called skinny repeal Wednesday. Another Republican from an expansion state, Sen. Dean Heller of Nevada indicated he would back it.
