Hello liberal supreme court, DC statehood, new VRA, national redistricting reform, immigration reform, etc!!!
You just listed a good part of my dream scenario, but I think it's going to be somewhat harder to pass Congressional gerrymandering reform than one might think. Democrats who believe they might lose their seat due to changes in the maps might refuse to vote for such a bill, so it would take quite a lot of incentives to get their support. Given that such a majority would very likely be be razor thin, it might not even be possible unless they can either get all Democratic House Reps on board, or poach a few Republicans who think they'll have an
easier time with fair maps.
I also wonder about DC statehood. As a former and hopefully again future resident, this is important to me, but I don't see much traction among the party despite the valuable edge it would give Democrats in the Senate.
