I think the big lesson learned from BBB/IRA/DOGE/Trump EOs is that whatever you decide to do, do it fast. The Biden initiatives, which I think were mostly good, were too slow. Too much process. You end up with (for example) a tiny number of EV chargers and states still doing broadband factfinding.
Lot to be said for pairing capitalization + statutory authority + permission to flexibly operate in the sector + removal of permitting or other process constraints on specific agencies meant to do investment. Filibuster doesn't let us do that. It needs to go.
I think it wlll be impossible to adequately undo the damage done by this administration without eliminating the filibuster. Which is OK with me because I think the filibuster is bad, but, assuming the Democrats get a majority in the Senate someday, you have to hope they agree.
