In the debate w/ Trump on June 27th Biden looked frail, stumbled as he spoke, hard to understand, was weak, confused and hesitant when speaking. He couldn't have fared worse. It's people's perception of the candidates is what counts; not the quality or lack thereof what they're saying. If Biden remains Trump's opponent in November the Dems may go down in flames. Lose the House and the Senate to the Repubs. They may never recover.
