They actually don’t have time. The first of the primary caucuses happen in less than a month. You’re talking about putting a full slate of unvetted candidates in front of a national primary with less than a month before voters would have to choose.

The Democrats made an error. They thought the Republicans surely would nominate someone else. They didn’t know Trump would quote Hitler a few days ago. They’re trying to run in an election with an incumbent. That’s how the parties have operated since… maybe the beginning. I don’t know that I know of a time when an eligible incumbent presidential candidate didn’t run. Maybe Washington?

Democrats are making the same mistake that voters are. They’re treating Trump like a beatable candidate, and expecting voters to act rationally. But yet, we see people saying the same irrational thing you are, that it’s better to sit out and let Trump get elected again than it is to vote for a milquetoast candidate like Biden. That’s it’s better for the worst evil to be elected than to vote for the lesser evil. It’s irrational. And yet, here we are, with someone thinking that the Dems can spin up a national primary for couple hundred million people in a couple of weeks.
