Schneider will likely win 52%-48% again. Don't see Dold winning in a Presidential year.
He does have Kirk (from his district) on statewide ballot in the Senate race. It's Dold's only hope, really.
Kirk only won this district 53%-43% in 2010 when he was winning statewide. If Kirk wins this district at all, it won't be enough to provide any coattails.
Plus, Kirk's never been the same since that stroke and seems to have acquired a bad case of foot-in-mouth. I don't think he's that much of an asset to Kirk anymore.
