The GOP leadership is desperate to get some kind of Obamacare repeal plan passed through the Senate. Senator John McCain, whose sad diagnosis of brain cancer was announced last week, is even returning to the Senate for the health care vote.

As the initial vote approached, it remained unclear exactly which version of the legislation Senate Majority Leader Mitch McConnell, R-Ky., would put in play. Republicans expect McCain to support taking up the measure, and his mere presence could make it harder for wavering Republicans to cast a vote against even considering the bill.

Keeping pressure on GOP senators, McConnell noted that many “made commitments to our constituents to provide relief from this failed left-wing experiment. And now we have a real opportunity to keep those commitments.” He added, “I hope everyone will seize the moment.”

Is this the “clean repeal” bill, or the “repeal and replace later” bill, or….??? No one quite seems to know what it will be.
