All good news. Restoring pre-clearance would be a huge deal.
As for the above discussion, I'll just say I see no evidence the reconciliation package on infrastructure will surely be 'watered down to nothing' and leave it at that. (It will come down from Bernie Sanders' price tag, but that's not the same thing). If this joint action causes McConnell, whose only goal is to ensure the Dems pass nothing substantive, to dig in and refuse to let any Republicans cross the line and vote for the bipartisan bill (assuming not enough defect to pass the worst possible bill), then this allows Biden and co. to simply throw up their hands, tell the Beltway 'we tried!' and With a Heavy Heart pass a big reconciliation package anyway. All he needs to do for Manchin, based on Manchin's past history, is show a good faith effort. When that fails, nine times out of ten Manchin votes for the reconciliation. And Sinema has already forsworn the same.
