Do you have more information about how the Court ruled on the census question? If the Court "nixed" the citizenship question from the census, then the Court ruled against the Trump administration, yes? How was the Court divided? And if the ruling on citizenship in some way counterbalances the ruling about gerrymandering, as your second statement suggests, then I assume that your third and last statement is directed at the gerrymandering ruling only, and you're not lumping the two decisions together as both "flushing democracy down the drain."
5-4 in both cases, Roberts sided with liberal Justices for the Census question.
The details are out there. Essentially Roberts thinks Trump government lied about the reasons for this change, so the Court awaits a better reasoning for a possible future ruling next year.
And of course only the gerrymandering decision merits excoriating.
It's remarkable that the this ruling is so appalling even the Conservative press (RedState, Breitbart, American Greatness, Fox), usually so responsive to anything that "makes libs cry", is too ashamed to focus on it!
