The bill would move money for ObamaCare's Medicaid expansion, tax credits and cost-sharing reduction subsidies to block grants to the states. It would also repeal the individual and employer mandates and the medical device tax.

On Friday morning, Cassidy told reporters that he was “pretty confident we’ll get there on the Republican side. We’re probably at 48-49 [votes] and talking to two or three more.”

The bill would have to surmount some tough hurdles in order to pass the Senate. The fast-track vehicle the GOP was using to repeal ObamaCare, since it avoided a Democratic filibuster, expires at the end of the month.

Additionally, the legislation could only afford to lose two GOP votes — assuming Vice President Pence swoops in to break a tie — and Paul is already a hard no.

On Monday, Paul told reporters the proposal would “probably” be worse than doing nothing about the health law. Over the summer, Paul was critical of GOP leadership’s repeal-and-replace bill, advocating for a clean repeal of ObamaCare instead.

“I think Mitch would vote for it, but he said, ‘Go get 50 votes,’” Graham said. Fifty votes would allow Vice President Pence to cast a tie-breaking vote.
