Tracker: Which topics were talked about the most at the 11th Democratic debate

What Joe Biden and Bernie Sanders talked about the most at the D.C. studio debate.

It was the coronavirus, climate change, the economy and immigration at the 11th Democratic debate. Joe Biden and Bernie Sanders faced off in the first one-on-one showdown of the 10-plus debates, which was held in a closed studio in Washington, D.C.

Biden and Sanders spent nearly 20 minutes of the two-hour debate discussing the virus, which has killed 67 people nationwide, shut down schools and sports leagues, and was what forced the candidates to debate while standing the CDC-recommended six feet apart.

Two other subjects linked to the virus – the economy and health care – were likewise among the most-discussed topics. The candidates spent just over 11 minutes discussing the economy and just over eight minutes on health care.

See the full breakdown of the debate below, which shows how much time the candidates spent talking about each of the topics.
