I agree, it seems this should be a non-issue.  But it is, and here we are.  I believe the dems don't want that question because so many districts would have to be redrawn, and become fewer districts, and states would lose seats in the HoR.  Which means other states would gain some.  And the dems are afraid that those new seats would go to Red states.  I think it is important to know how many illegals we have in the country.
