The SCOTUS today will hear arguments on the Census. Essentially, Hair Füror only wants to count US Citizens, while traditionally (at least since the 13th Amendment kicked-in) it was all free persons in the United States, not just citizens.
This will be a test for the so-called Constitutional literalists who mostly are Republicans (and mostly ideological Republicans at that) as undocumented people tend to be people of color. Expect some eff’ery.
(Hair Füror’s pocket Nazi Stephan Miller is probably the mastermind behind this, and would like to return to the 3/5s days of yore.)
