I've got news for them, all these people have already been voting, illegally, but doing it anyway. This isn't going to help them much.
Why do you think there is nothing in the census form package to either ask if the respondent is a citizen, nor to state that they must be one to be counted.
Nothing.
So they are all getting counted, and the entire (half of the question space on my form) nit-pick about race, what brand of spanish-speaker you are, etc. is about gerrymandering the districts so the race blocs (especially certain groups) can vote to negate the other people of other races in a majority of districts in some areas where the mix will allow that. It will also tell the GOvernment where to offer the best perks for ethnic groups to imporve the 'mix'.
Thank God we are 'blessed' with some of the worst winters in the lower 48. It keeps the riff-raff out.
