Why Joe Biden’s campaign is a slow-motion disaster

Joe Biden is still hanging onto the frontrunner spot among the Democrats running for president, despite his less-than-stellar debate performances and regular gaffes. He’s also fighting surging enthusiasm from the progressive wing of the party, which sees him as a vestige of the old Democratic party they loathe almost as much as they loathe President Trump.

It all calls into question the main argument that Biden’s pitching to voters: that he’s the only Democrat who can beat President Trump.
