So, how many illegals are in the country and are they concentrated in such a way to shift the numbers of representatives in an indefensible way? Oh, that's right - it's racist to want to know
It's not racist, it's just difficult.
They are not counted or registered anywhere unless they get arrested.
And expecting illegals to self-report during the census is ridiculous.
They can claim to be US citizens if they want, no proof of citizenship or status is required.
It's just like wanted to know how many Americans are part of the organized crime.
