I interpret these numbers as meaning one Dem seat in Illinois out of those listed is in serious play. I suspect the bulk of the undecideds, if that way at this point in time, are going to tilt to the Dem incumbents by election day.
So these numbers "feel" right to you Muon2?
They have Obama with a 50-47 disapproval. I would guess that the right number is closer to 55-42 approval. If that's the case, the other numbers should be shifted accordingly. Also, this was taken some time ago, and I think that the health care vote mat have some effect on the next poll as well.
Are those Obama approval numbers for IL statewide or only these districts? I can't tell from their website.
