Chicago has had a history of corrupt voting in the 60s no doubt, but I have not heard of verified evidence that there is widespread voting of illegals. And no, I don’t consider right wing blogs as evidence. You do need ID to vote (I have always been asked for one) and your anecdotal story does not prove that “Illegals vote all the time.”
I think you just hate immigrants cause your lazy or stupid and can’t compete for the low end jobs they take.
