As self-evident as it may seem to liberals that the Trump presidency has been a disaster and is doomed to defeat, the daily cycle of scandal and outrage that dominates social media is no substitute for a viable presidential candidate. And the Democratic Party, it seems, has yet to learn the key lessons of Hillary Clinton’s failure in 2016. While Donald Trump has already filed paperwork for his re-election campaign, Democrats are facing a distressingly shallow bench of potential challengers. Trump may be flirting with an all-time low approval rating, but many of the politicians maneuvering to challenge him are not necessarily in a much stronger position.

There are the usual buzzed-about hopefuls, of course, that remain beloved on the left, including Joe Biden, who just launched his own political action committee, and Elizabeth Warren, whose progressive credentials are unimpeachable. But Biden would be 78 by the time he would assume the presidency, and Warren—whether or not you believe her—has said repeatedly that she isn’t running. The remaining names on the 2020 shortlist, meanwhile, are a pretty motley crew—and sure to leave a bad taste in many liberals’ mouths.

Axios’s Mike Allen surveys the field:

Virginia Gov. Terry McAuliffe: He has talked extensively with friends and advisers about running. The guy has boundless energy, ambition and access to money — and the personality and love of the game to withstand the grind and glare of politics.

Sen. Kirsten Gillibrand (N.Y.): She has met privately with top party officials and just hit California to raise money and her profile. Make no mistake: She wants to run. But that doesn't mean she will.

Mark Cuban: He considers himself a smarter, better-looking and more authentic version of Trump. He has coin, ambition and comfort in his own skin. Of all the CEO/celebrities, he's the most likely to plunge into the shark tank of politics.
