Biden's VP Search Puts Spotlight on How Long He'll Serve Associated Press Joe Biden has longed to win the White House for more than three decades. If he finally makes it there after November's election, he's already talking about leaving. In an effort to ease concerns about his age, the 77-year-old presumptive Democratic nominee has said he wouldn't seek reelection if his mental or physical health declined. He has also referred to himself as a "transition candidate," acting as a bridge to a younger generation of leadership. Biden is rarely known for sticking to a script, and the comments are evidence of his candid style. But they're also contributing to intense speculation about who is best positioned to lead the party after him. "We do have a longer bench as Democrats, a younger bench in terms of elected leadership all across the country," said Democratic strategist L. Joy Williams, chairwoman of Higher Heights PAC, which is dedicated to electing more women to national and statewide offices. Biden has not ruled out running for a second term, in part because such an explicit pledge would immediately render him a lame duck in Washington, where political capital will be needed to manage the coronavirus recovery. But the question of his long-term prospects looms over his candidacy, especially as he considers his options for vice president. .
