How to Beat Joe Biden

Can his rivals fracture or overwhelm his coalition?

But the approach has a certain strategic logic. It assumes that activists can be appeased with specific promises, while the moderation of many older Democrats manifests itself more in general cultural attitudes (the kids these days with their political correctness, grumble grumble) than detailed policy preferences. It assumes that absorbing a certain kind of attack from the left — Biden’s too nostalgic for the bad old days, Biden’s a chump if he thinks he can cut deals with Republicans helps with voters who are nostalgic for the days of dealmaking themselves, without making it impossible to eventually unite the party in the way that staking out heretical positions might.

These assumptions are by no means crazy. But it is also very easy to see how they might fail. Biden is hardly the most formidable of front-runners, and if any piece of the current coalition breaks off, he’ll be in deep trouble. And his rivals have obvious plays that might make that breakup happen.

The first play is to split off some of Biden’s African-American support by linking his nostalgia for dealmaking to his less-than-progressive record on race. This is the play Cory Booker is trying to execute, and Booker’s campaign probably depends on its success — which is by no means foreordained, since the African-American vote is more conservative and Biden-friendly than the median white liberal. But nobody before his years as Obama’s V.P. would have regarded Biden as a natural destination for the black vote, and enough sustained tone-deafness in the present could make that past matter once again.

The second play is to make the broader “Uncle Joe” persona, not just its unwoke element, a liability for Biden’s elect-me-to-beat-Trump case. This is probably the Pete Buttigieg play, though it’s available to any younger candidate: Without saying so directly, establish contrasts that make Biden look old, confused, a man out of time, even Trump-y in his own right. Don’t challenge his record, don’t call him a troglodyte — just challenge the conceit that a likable but past-his-prime uncle makes the right contrast with Trump.

The third play is to attack Biden from the center when he flip-flops, and try to break off his more conservative supporters by arguing that the former V.P. isn’t the moderate he used to be. This should be an obvious move for the legion of candidates (Amy Klobuchar, Tim Ryan, Seth Moulton, Michael Bennet, etc.) lining up to inherit the moderate torch if Biden’s campaign fails. But I suspect it will be hard for them to execute, because none of them seem eager to fight the activist left either. (The once pro-life Ryan, for instance, has flipped on the Hyde Amendment as well.) Still, every time Biden decides to check an ideological box, he leaves this flank exposed.

And the fourth play — well, the fourth play doesn’t actually require breaking up Biden’s current coalition; it just requires uniting a slightly-larger portion of the party against him.

We have an example of how not to do this in the failed attempts by Ted Cruz and Marco Rubio to unite Republican primary voters against Donald Trump. But in the rising line of Elizabeth Warren’s polling support, and the flat or falling lines of all the other non-Biden candidates, you can see at least the beginning of how NeverBiden might unite, and win.
