I think the Dems are smoking crack if they think they can force that through...
Manchin has already come out hard in opposition to it, and I believe there are a couple other Dems in smaller Red states who are leaning the same way.
The Democrat from a small Red state is an important consideration, because they know that this would be about as devastating to small state influence in the political arena as the elimination of the Electoral College or pulling DC in as a full state.
