The networks are allowing Trump to spin and bullshit his way through this crisis on a daily basis**, and in so doing influence the stupid and the gullible in this country, which unfortunately represents a significant percentage of voters. They’re basically giving him free campaign commercials each and every day, and allowing him the opportunity to spread his “fake news” crap whenever he gets into a dispute with an aggressive questioner.
Meanwhile Uncle Joe Biden does interviews and records an occasional policy video from his home studio. Dynamically speaking he’s basically faded from view.
** In the words of Philadelphia Inquirer columnist Will Bunch, “night after night [we’re getting] self-serving bluster and blame deflection, a dose of dangerous medical hucksterism, and more yelling at journalists, especially if the journalist is a woman or black or, heaven forbid, both.”
