President Obama is in the final hours of his campaign, but he's taking time to wish some fellow Democrats good luck down the stretch. Aboard Air Force One from Concord, Mass., to Fort Lauderdale, Fla., Obama called Senate candidate Elizabeth Warren of Massachusetts, according to her Twitter account: 


Warren is locked in a tight race with Republican incumbent Scott Brown, though recent polls have shown her taking a slight lead. One poll by the Springfield Republican released Sunday showed her leading by four points, 50 percent to 46. The White House and Obama campaign have not yet commented on the president's high-flying phone call of support.
