IIRC thery inserted a provision in one of the bills that says it needs 67 votes to overturn. IMHO that will be struck down by the SCOTUSA because to reengineer Senate rules you need a vote of 67 not 60 as it was passed with. All I can guess is that they want a washout in November and want every seat up for reelection to go republican.Unless of course they believe their pollsters who seem to be in direct conflict to every other poll out there?
In order to get a super majority provision, you need a super majority to pass it.
Let them keep believeing their pollsters as they lose big this November and then they can ask can that happen as the people were supposed to like healthcare once it is passed.
