They don’t need 60 votes, they only need 51, if they repeal if by the same “reconciliation” gambit that was used to pass it in the first place. If someone objects, the response is that if the objection is correct, it was never legally passed in the first place.
You are right and McConnell is full of crap. The Republicans could pass a bill repealing 0bamacare and send the bill to the White House with 51 votes. 0bama would veto the repeal. Maybe some Democrats would not want to vote for 0bamacare a second time and vote to override the veto. McConnell is worthless. Pass the repeal and put the Democrat senators in an uncomfortable position.
