Former Virginia Republican Congressman Tom Davis, whose knowledge of electoral politics is impressively encyclopedic, told National Review Online that if a Republican manages to win back his old 11th District seat in November, the GOP will regain control of the House:

“Davis, who ran the National Republican Congressional Committee for four years a decade ago, believes this district is roughly the 45th most difficult pickup for the GOP. On that reckoning, if the Republican candidate carries the 11th district, the GOP will control the House of Representatives next year.”
