You can't dismiss every poll because of what happened in Michigan. The Cook County suburbs are much wealthier than the Detroit suburbs and they aren't going to vote for someone who wants to raise taxes through the roof. It's an entirely different ballgame in Illinois.
Kind of irrelevant, as they'll be voting in the GOP primaries.
The rich liberal Protestants, Catholics, and Evangelicals will be voting in the GOP primaries, but the rich Jews and atheists/agnostics will for the most part vote in the Dem primary. I remember in Mr. Illini's map series how there were very wealthy parts of suburban Chicago that voted for Pat Quinn, and usually it was tightly correlated with Jewish population. I think it'll hurt Sanders a little bit, but not as much as Invisible Obama is suggesting.
Indeed, RINO Tom, Chicagoland is not Peoria. In fact, if you totaled the precincts of Chicago's North Shore, the wealthiest area in the Midwest, you would find that Obama won a majority of the votes both times.
Expect the entire North Shore to be solid Clinton territory in the Democratic Primary. Expect Kasich to perform well there on the other side.
