I’m Karen Tumulty, and this is Round 13. I’m not particularly superstitious, but I’d still advise Beto to keep standing on top of tables rather than under ladders.

The Commentary

With former vice president Joe Biden finally in the race and taking the pole position as the early front-runner, an enormous field of 20 candidates has taken shape. Pundits and political journalists are dusting off the old trope that each challenger is trying to find a “lane.”

You know what I’m talking about — cable television is full of chatter about the establishment lane, the insurgent one, the populist pick, the candidate of a particular gender or ethnicity.

Except that this is rarely, if ever, how it works. Voters — not even the stalwarts who come out during party primaries — do not tend to pick categories. They pick candidates. Over the next year, some of these contenders will shine; others will stumble; still more will simply disappear. I expect that by the fall, a half-dozen or more will drop out, either because they aren’t raising any money or because they remain asterisks in the polls.

In 2016, Donald Trump did not wipe out a field of 16 other Republicans by picking a lane. He did it by bulldozing an entire new highway for himself, using as his steamroller the grievances of voters who believed they had been ignored or looked down on for too long.

Eight years before, Barack Obama knocked off the redoubtable Hillary Clinton in the 2008 Democratic primaries not by tactical positioning but by winning in homogeneously white Iowa. That surprising victory made his party believe that perhaps the moment — and the candidate — had arrived to show that America was ready to elect its first black president.

It is far from clear which candidate best suits the juncture at which the party now finds itself. One thing the polls tell us is that rank-and-file Democrats are more concerned about finding a winner against Trump than they are about specific positions on the issues, ideology or diversity.

As much as Biden is being touted as the figure who has the best shot of winning back non-college-educated white voters in the Upper Midwest, I think his most powerful message may be the one he emphasized in his announcement video: Trump’s moral failings. That’s not a lane; it’s an imperative for whoever wins the nomination.
