Activists pushing for the impeachment of President Bush were dealt a blow this week in their quest to unseat West side Democratic congressman Jerry Nadler. His opponent Adam Sullivan – whose nascent campaign arose out of outrage at Nadler’s refusal to hold hearings to investigate impeaching Bush – has run into a little snag. In the rush to launch his campaign, Sullivan, who previously had no political affiliation, didn't understand that it was too late to register as a Democrat and run in November! Sharon Lynch from the Sullivan camp tells us he’s having a meeting tonight to decide the future of the campaign: “We're grassroots activists with full time jobs outside politics; in the rush to field a challenger we missed this.”
