Sanders pledges to support Democratic nominee in 2020

“If we do not win, I will strongly support the Democratic nominee…and hope and believe that others feel exactly the same way. Donald Trump must be defeated,” Sanders said Saturday while campaigning in Iowa.

Sanders, who unsuccessfully ran against Hillary Clinton in the Democratic primary in 2016, was roundly criticized by the party establishment for what some said was a lackluster effort to support Clinton after it was clear he had fallen short of the needed delegates.
