Voter registration already informs the state how many voters there are.
Ok but how do they do voter registration? It has no relation to the census?
The question is intended to intimidate.
There's significant evidence that the GOP wants to add this question because they know it will reduce participation in the census, making their gerrymandering efforts even more effective.
I'm aware of the intimidation aspect. But non-citizens can't vote, so how would that help gerrymandering?
