I'm curious about what made Manchin balk. All I've read had been secretive. "the staffers know what I'm talking about"
I don't like his politics, but I don't blame Manchin at all. He's been remarkably consistent since summer that he's willing to get onboard with a skinny $1.5T bill. Biden talked him into bumping that to $1.75T, but Manchin is only willing to pass a bill without accounting tricks to conceal the true 10-year cost. CBO scored the CTC as $1.6T over ten years alone.
Obviously the part we all dislike is that his energy policy is going to block carbon emissions reduction, which will have disastrous consequences long-term. Some are accusing him of not bargaining in good faith over BBB, but I don't see that.
We have to understand that Manchin is only king for a year because Stacey Abrams engineered the two upsets for the Senate seats of Georgia. Realistically, we were going to lose one or both run-offs and McConnell would still be the obstructor in chief. And like Manchin said, if the Democrats had a better majority in the Senate, Manchin's willingness to deal or to obstruct would be irrelevant: "elect more liberals" is what Manchin said about passing progressive legislation.
Sadly we're fucked for the midterms, and then Joe Manchin will have no juice after that.
