Four Republicans block Obamacare repeal bill in Senate Moran and Lee are the latest to say they won't let this version of the bill move to the Senate floor. http://www.politico.com/story/2017/07/17/obamacare-senators-turn-on-mcconnell-240646 Republican Sens. Mike Lee and Jerry Moran said Monday night they will join two other senators to oppose the Obamacare repeal bill, dooming the GOP initiative in the Senate. Republican leaders could only afford to lose two senators on the procedural motion to start debate on the bill. Lee and Moran would join Sens. Susan Collins and Rand Paul in opposition to the version of the bill currently before the Senate. But with four senators declared "no" votes – and several more undecided – Senate Republicans wouldn’t have enough votes to even start debate on repealing Obamacare, the campaign promise they have made to voters for seven years.
