Democrats have claimed victories over the final House seats that remained undecided from this year’s elections. Overall, Democrats gained a total of eight seats, tightening the Republican majority in the House of Representatives. Two closely watched races in California saw Democrats oust Republican incumbents Dan Lungren and Brian Bilbray. In Arizona, Ron Barber, a former aide to Democrat Gabrielle Giffords, has been re-elected after initially replacing Giffords following her shooting in last year’s Tucson shooting rampage. Meanwhile, in Florida, tea party-backed Republican Congressmember Allen West has finally conceded his re-election bid against Democrat Patrick Murphy following two partial recounts.
