WASHINGTON (AP) – Sunday’s Democratic presidential debate is likely to be dominated by the mounting coronavirus crisis. Just two candidates are left in the Democratic race: former Vice President Joe Biden and Vermont Sen. Bernie Sanders. They’ll debate in a television studio in Washington without an in-person audience. The debate was moved from Arizona because of concerns about cross-country travel. It’s the first Democratic debate in two-and-a-half weeks, and the first since Biden took command of the primary race.
