In Thursday’s Democratic primary debate, Elizabeth Warren logged the most speaking time, followed by Amy Klobuchar, Bernie Sanders, and Pete Buttigieg. None of these candidates are the Democratic front-runner.

Joe Biden is, but we heard little from him during the debate — and perhaps that’s a good thing. The less Biden speaks, the more likely it is that he’ll maintain his front-runner status. The former vice president is familiar and friendly, but he is also prone to gaffes that have opened him up to criticism from Republicans and Democrats alike.
