It only takes one to say no, because otherwise they don't have enough votes.
That isn't true. They can have either one or two No's and still pass it. They can also, and I can't emphasize this enough because you don't seem to understand this part, change the bill to get more votes.
It isn't a stone tablet that must be voted on as-is. It should also be noted that the Senate version does not repeal the EV tax credit
, so that point is moot. The Senate bill will likely pass (after modification) for these reasons, and the Conference Committee will then have to decide if the credit stays or goes. With almost all of the Republicans in the House and most of the Republicans in the Senate supporting ending it, I just don't see an outcome that keeps the credit. Only a complete failure to pass a budget is likely to maybe save the credit, and even then it can still be killed retroactive to 1/1/2018
when a budget does eventually pass.
