Apparently it was 6-3, so that ruled out the "recusing to hang the verdict" anyways.
What was this ruling that supposedly cut out 4th amendment for all the other agencies? All I recall hearing is the whole border zone thing and it's hard to make a point about it if you can't provide the source.
As for holding the Senate and House, honestly the best option at this point is to make a concentrated attempt to take control of all state legislatures. If we're going to try to use the ballot box still, local and state elections just became 10000% more important, especially since that's how the Rs involved got their power in the first place - taking the local and state elections then using that to gain leverage for Federal. Unless you can get a Constitutional amendment(which requires 2/3 states to ratify it IIRC) pushed through, any Federal laws rely on either interpreting those amendments(which relies on the SC) or the Commerce clause, which relies on interstate commerce being able to be directly linked to whatever it is. Or funding withholding, I suppose, but doesn't have the same force of law that the either two approaches have.
Honestly it IS time for another amendment, but good luck getting it without getting enough of the right people into the right positions in state government.
