The early Democratic presidential contest has been an exercise of lefter-than-thou politics, culminating in the earnest consideration of 70 percent tax rates and wealth confiscation for émigrés.
You can understand the temptation: Trump seems weak, perhaps already doomed. Why compromise with the faint of heart? Give the American people a choice, not an echo!
This is the logic of factional politics. You want the smallest possible majority, most easily dominated by its most mobilized minority. That’s how the Tea Party thought during the Obama years, that’s how the Trump campaign evolved in 2016. Sometimes it can work, at least if you catch a lucky bounce.
But if you seriously believe that the Trump presidency presents a unique threat to American democracy, you want the safer choice, not the risky one. You want the candidate with the broadest possible appeal, not the most sectarian. Trump will be beaten not by his fiercest enemies, but by his softest supporters. You want to appeal to them, detach them—not chatter on social media about how you’d like to punch their kids in the face.
