I live in Del. Rob Bell’s district, the 58th, and I’ve been keeping an eye on the voting trends here. Perriello defeated Goode in this district by 25,826 votes to 20,996 votes, or with 55% of the vote. (Note that Orange County is not in the 5th Congressional District, so I substituted the presidential numbers for those two precincts. McCain won both by comfortable margins.) Those are the sort of numbers that support a Democratic challenger.
It seems that Bell is aware of this shift—we just got a sort of a random mailer from him about veterans’ affairs, the first such thing I think we’ve ever had sent to our house. It was postmarked November 5.
