RE: Trump says he’s devised another path to the same information

Yes, but my main question is still this -— Will such information, once gathered be used to apportion electoral votes as the census does?

If not, then it will all be just an academic exercise, useful, but not effective in practice.

"Will such information, once gathered be used to apportion electoral votes as the census does"

One answer to your question is another question: if Trump can't get a citizenship question on the census, can the 2020 Census be invalidated by showing with other government data that it doesn't accurately capture population results?
