 Lloyd Doggett represents a very blue district based in Austin. He says Biden has been running behind Democratic senators in key states and has been trailing GOP presumptive nominee Donald Trump in some key places. He hoped the debate would change that, and it didn't. Doggett says his move to make his concerns public doesn't diminish his respect for the president, but Biden's first commitment should be to, quote, our country, not himself. The Biden campaign did not immediately respond to a request for comment.
