Maybe we should adopt some sort of compromise—say, a non-citizen counts as three-fifths of a person in the census. Of course we wouldn't allow them to vote, but then the states where a lot of them live would have greater representation in Congress, and the voting citizens of those states would have greater power than the citizens of other states. That's only fair—right?—because they're "voting for two," so to speak. Well, voting for one and three-fifths, maybe, but you get my drift.

I seem to recall this was tried somewhere before....
