As I look at the 2020 Democratic primary field, I’m reminded of the 2017 French presidential election. Do you remember? In the first round, the Left Party’s candidate, Jean-Luc Mélenchon, got 19.6% of the vote, failing to secure the 21.3% he needed to beat Marine Le Pen and advance to the second round. Mélenchon just narrowly missed the boat because he didn’t command the whole left block. 6.4% of French voters instead picked the Socialist Party’s candidate, Benoît Hamon. A further 1.7% of French voters chose the candidates of the Communist Union or New Anticapitalist Party. The left could have commanded as much as 27.7%. It only needed about a fifth of these additional left-leaning voters to slip past Le Pen. But these left wing candidates refused to drop out of the race, and the result was a depressing second round, in which the only alternative to France’s status quo was right nationalism. So when I look at the Democratic Party’s field, I ask myself–who is the Mélenchon, and who are the Hamons?
