Ben Smith reports that Virginia senator Jim Webb won't seek reelection in 2012:
Virginia Senator Jim Webb plans to announce today that he won't seek reelection, a senior Senate source said.
Webb appeared likely to face a rematch with former Senator George Allen, whom he beat in a bruising 2006 contest. He had expressed ambivalence about the prospect of another run, and has said he never planned a life in politics.
Senate Democratic leaders view Democratic National Committee ChairmanTim Kaine, the former Virginia governor, as a top prospect to replace him, despite Kaine's disavowals that he's looking at the race.
