RealClearPolitics has a long column arguing for the Census to count only US citizens, which hasn't been the practice in the past. I find the arguments favoring this change persuasive, perhaps you will as well.
Much of the anti-ICE rhetoric in Congress has come from big city Democrat Representatives representing their (non-citizen) constituents who by law, of course, are not permitted to vote.
Trump tried to change to citizen-only counting for the 2020 census and failed by one vote in the Supreme Court. The Court now has a originalist majority and he should get the change locked in place sooner rather than later.
