Bernie is likely going to win here in Illinois, but I get the feeling that this poll is oversampling downstate, considering the over-performance on behalf of Sanders and Cruz.
Out in the western burbs of Chicago, Bernie signs are everywhere and there's nothing for Hillary. There's not really much of any Pub Pres candidates either and this is usually 60-40 Pub territory. It seems like every Dem house I know has a Bernie sign.
Will be interesting to see if Bernie takes any of the collar counties. In Michigan we saw Hillary win Wayne and Oakland, yet he still won the state. Eager to see how Lake and DuPage vote.
