It took way longer than expected to call, but Virginia Democrat Mark Warner has kept his seat in the Senate. Republican challenger Ed Gillespie conceded the race today, reports Politico. Warner had been expected to easily win re-election, but he managed an advantage of only about 16,000 votes out of 2 million cast, reports the AP. This leaves only the races in Alaska (too close to call) and Louisiana (headed to a runoff) still up in the air. Both seats are currently held by Democrats, meaning Republicans can only build on their new Senate majority. They control 52 seats at the moment.
