hi csl,
good one.
fortunately, pollsters usually sample a few more folks than csl's friends.
illinois, as you know, shows o +19-20%. in chicago the dems have the blacks, latinos and unions, as well as hordes of dependents with pre-existing conditions (and lots of children)!! ;-)
in general, i'm expecting poor exit polls for obama, as he has been getting dem votes done early. meaning this is likely to be more of a republican day than most.
