Biden is for all practical purposes is the party's presidential nominee with the last major candidate, Senator Bernie Sanders, dropping out.
He will sail through Democratic National Convention nominating process, once the leaders figure out how to conduct the event scheduled for August during the Coronavirus pandemic.
Sanders, a self-described socialist, has endorsed Biden, and so has Senator Elizabeth Warren, another candidate from the left for the party's nomination, who dropped out.
Those endorsements could rally the party's left-progressive ranks around Biden, the centrist establishment candidate.
Trump has monopolised the public discourse with his daily briefings with the White House Coronavirus Task Force, while Biden is shut out unable to hold rallies.
The town hall meetings are one way for him to get exposure in the national media.
