The first 2020 presidential debates will happen this week. On Wednesday and Thursday nights, NBC will host two separate debates, featuring 20 candidates across the two nights. The moderators will be Savannah Guthrie, Lester Holt, Chuck Todd, Rachel Maddow and José Diaz-Balart.

I think it’s important to acknowledge that the journalists who moderated the presidential debates in 2016 didn’t do an especially good job.
