Thanks for your comment. I read about the report that Biden had a cold. I am not a nurse, but I also thought he looked ill when he walked to his podium.
Biden was at his best during the State of the Union address. I want to hope that Biden is still possible, but I fear that he is not. That is why I am hopeful party leaders take a hard look at the possibility of selecting another candidate.
Were Biden to stumble at the 2nd debate in September (if he still participates), the election will be over.
