 I had hoped that the debate would provide some momentum to change that. It did not. Instead of reassuring voters, the president failed to effectively defend his many accomplishments and expose Trump's many lies. Doggett, 77 years old, is the first Democratic member of Congress to call for Biden to withdraw from the ticket since his debate. Congressman Dean Phillips, Democrat of Minnesota, ran a challenge against Biden in the Democratic primaries, but has stayed muted since the debate. That was from the Texas Tribune.
