I always expected Senator Joe Manchin to budge off his hard cap of $1.5 trillion in spending for the Build Back Better budget reconciliation bill, and he’s now making mouth-noises that will permit something in the range of $1.9 to $2.2 trillion. I think everyone will settle in that range, and it should be enough to enact a truly Rooseveltian level of transformative change.

But that’s not what could still sink the whole effort. Manchin has some policy no-gos and a policy demand that progressives are going to have real difficulties accepting. He’s against implementing a carbon tax, but that could be a key way of making the numbers work. After all, Manchin doesn’t want to borrow the money for this bill and it has to be funded somehow. Then there’s this:

Another major difference is Manchin’s insistence that natural gas be eligible for grants under the $150 billion Clean Electricity Performance Program, a core component of the reconciliation bill’s attempt to combat climate change.

On the whole, Manchin has the keys to environmental policy as the chairman of the Senate Energy & Natural Resources Committee, and he’s not going to allow green policies that are adequate to our climate change challenges.

Yet, the biggest hurdle is probably the Hyde Amendment.

One major sticking point is his insistence that the reconciliation bill include the Hyde Amendment, which prohibits using federal funds for abortion expenses.

[Sen. Elizabeth] Warren has criticized the Hyde Amendment as disproportionately affecting low-income women since it prohibits Medicaid from funding abortion.

That’s a problem because if Manchin insists on this point, the progressives may not provide the votes needed to pass the bill in the House. .

Representative Pramila Jayapal (D., Wash.), chair of the progressive caucus, said Sunday that she will not support Democrats’ massive social-spending package if it includes the Hyde Amendment, a stipulation that prohibits taxpayer money from funding abortions.

But the difficult truth is that Manchin has an absolute veto. Technically, every Democratic senator has an absolute veto, but Manchin is the one most willing to walk away from the Build Back Better agenda. You can have lower child care, health care, education, housing and prescription drug costs but Manchin says that’s a package deal that comes with the Hyde Amendment.

Anyway you look at it, this bill is going to come up short of what we’d like. The price of getting it done will absolutely include some stomach-churning compromises and there will be both issues and constituencies that have very real grievances.

I can’t stand here and tell people that they have to support a bill that sells them short or leaves them out, but it really is pretty important that the Democrats don’t come out of this empty-handed.
