Don't think it doesn't matter. Your choices are few.There are some Green Party challengers and even fewer Republicans in Chicago. We effectively have a one party system in this city and county, and if this were the Federal Government we'd start a revolution. So few people vote here, so your vote does make a differnce. True Chicagoans vote.
