Don’t be surprised if McCain votes against anything. His buddy, Linda, will follow. Collins will vote her usual Demo style. If all other 49 repubs vote for anything there will not be Pence to the rescue.
I think he sent clear signal that he wants to create a block of democrats and republicans to position themselves to create an end product that he can take credit for. like he has in the past, he will try and control the outcome by forging a coalition. I expect we will end up with a very liberal outcome.
