He is playing possum waiting for an opening.
Here is the way I see it:

1) he has already intimidated a lot of people who are justifiably scared of being caught.

2) The census will go on as relatively normal.

3) Now here is where I am not sure about procedures, but redistricting will take place in 2021.

4) Trump has already said that they will get non-citizen populations from "other sources"

5) Whatever agency (Commerce dept?) that conveys the populations to the state will subtract non-citizen populations from state totals. I am guessing they can do this down to a county or maybe even lower level.

6) Trump will issue an executive order that redistricting is to be done based on the "citizen numbers"

7) Sure there will be a lawsuit - it may be filed before the election.

8) we have to get that SOB out.

I suspect that the "other sources" for populations will include voter roll that have been subject to the Kobach cross check system. That should cut a substantial number.

I don't think they are done with this by any means. No doubt RW think tanks will be have this as a top priority.
