Former Vice President Joe Biden to make third run for the White House
Former Vice President Joe Biden, a moderate Democrat who has made his appeal to the disaffected working-class voters who deserted the party in 2016 a key part of his political identity, is set to launch his third run for the White House on Thursday.
Biden will announce his bid by video, according to a source familiar with the plans. He then is expected to make his first public appearance as a candidate on Monday at an event in Pittsburgh featuring union members, a key constituency.
