Updated 3:45 p.m. | Former Virginia Sen. John Warner is crossing party lines to support Democratic Sen. Mark Warner's re-election campaign this year. Warner, a former five-term Republican senator, told the Associated Press on Monday he is backing his successor in the Senate over former Republican National Committee Chairman Ed Gillespie. Speaking later with CQ Roll Call, John Warner said he encouraged Mark Warner to seek re-election, citing the state's need for seniority in the Senate. "I’m not jumping my traces," John Warner said. "I’m just exercising what I think is a responsible judgment, because Mark Warner is gaining seniority and stature, and has a proven ability to cross the aisle and make things happen." The two Warners faced off in a 1996 Senate race, with the incumbent holding on by a 5-point margin. After the loss, Mark Warner went on to win a term as governor in 2001, before running again for the Senate seat of the retiring John Warner. This is the second time this cycle the former Republican senator has backed a Democratic Senate candidate. Warner contributed to the campaign of Michelle Nunn, the daughter of former Democratic Sen. Sam Nunn, who is running for an open seat in Georgia. (more…)
