I feel like the thing that needs to be said here is: BBB, in its current form, was hot garbage.
Partly, it's the fault of Manchin and other moderate Dems, who peeled away funding and forced the size of the package to shrink, meaning there was no feasible way to do everything on the agenda and do it well. So at that point, Dems could've picked a few important things and fully funded them. It would be
something. But instead they tried to jam everything in as temporary programs that, like the CTC, would expire after a while. The fact that everyone is now preparing for the CTC's expiration next year is all the evidence we need to see why that's a good idea.
So the best thing Manchin's done in this whole process was to look at that funding scheme and say "not gonna support that, it's bullshit." That was the Dems' chance to go back and do what they should've done, which is pick a few priorities and call it a win.
And now, in the midst of all the drama since Sunday, we find out that Manchin
did give the White House a proposal along those lines:
Sunday morning,
Joe Manchin threw a giant twist into the plot of the Biden presidency by announcing his opposition to the administration’s signature domestic agenda. But the new plot had a gaping hole: Biden noted that, a few days before walking away, Manchin had made a counteroffer to Biden at the White House.
What was the counteroffer? And why did Biden reject it?
The Washington
Post fills in the answer. Manchin’s proposal included universal pre-kindergarten, an expansion of the Affordable Care Act, and hundreds of billions of dollars in green energy spending, all totaling the promised $1.8 trillion.
Manchin apparently doesn't support funding/extending the CTC because he thinks poor people are gonna spend it on booze or whatever, so he's a classist asshole, but the important part is that there was a viable path to getting something done and signed into law! And it includes something to address climate change, which is probably the most pressing issue of all.
But of course it's all spiraling into drama and disorder because the Democrats are the Detroit Lions of political parties.
