It now appears as many as six Republican Senators could vote "no" and possible more. That would give them no more than forty-six votes, and that's not enough -- this measure needs at least fifty to pass.
At the same time, the bill's sponsors amended the proposed legislation over the weekend with state-specific sweetners in an attempt to turn some "no" votes into "yes." So this is becoming a real cliffhanger.
If you are at all interested or concerned about this issue, CNN is hosting a live town hall tonight featuring the two senators who sponsored this horrible bill debating Independent Senator Bernie Sanders and Democratic Senator Amy Klobuchar (details here). The debate is scheduled to begin at 9 p.m. ET, at 6 p.m. PT.
