I wasn't actually referring to the parliamentarian...I was actually speaking to a more fundamental level, that Democrats don't have 50 votes to pass a bill with a $15 minimum wage, even if the parliamentarian signed off. I thought the issue boiled down to just Manchin and Sinema, but I heard today that Bernie Sanders' proposed amendment to add the $15 minimum wage was voted against by, I think, 6 Democrats.
This is extremely disappointing to me, but I don't really see how it's Joe Biden's fault. It would be his fault if he lobbied against it or refused to sign a bill that reached him. This is an issue (which I mentioned during the primaries) of the median Senator being more conservative than all the major Democratic candidates (I don't count Bloomberg as a "major" candidate, as I never thought he had a hope of winning the nomination). This is why, while I preferred Sanders to Biden, I didn't actually think which of the two won mattered a great deal in terms of passed legislation. Sure, Sanders would be much more progressive in his beliefs--that just means that much more progressive priorities would die on the Senate floor. If you can't pass even a complete Biden agenda, what's the point of a Sanders agenda? (The answer, IMO, is that there's still value in having a President arguing for those things with the pulpit of the position, which is why I did prefer Sanders as President.)
