With just six candidates, tonight’s Democratic debate in Des Moines, Iowa, will feature the smallest—and whitest—lineup this election cycle. (Andrew Yang missed the polling threshold, and Cory Booker ended his campaign on Monday.)

To guide you through the debate, which CNN will co-host with the Des Moines Register, we’ve rounded up the top liberal and conservative commentators below. You’ll see liberal tweets on the left and conservative tweets on the right.
