Mary Kate Cary, a senior fellow at UVA’s Miller Center and a former speechwriter for former President George H.W. Bush, said she understands why Biden may think voters want a president who doesn't make news for what he's tweeting. But putting out safe tweets that are unlikely to cause controversy also takes away the opportunity to showcase his "personality and humor," Cary said, and with limited press conferences Biden could "fill the gap" with Twitter.
