Now Biden’s back on the campaign trail, and no one could be more thrilled than the Chinese Communist Party. (A Forbes headline last year summed up the situation well: “Joe Biden Is the Only Man Who Can Save China in 2020.”) Biden’s announcement of his campaign alone was enough to encourage Beijing suddenly to take a harder line on trade negotiations with the Trump administration.

While it is true that Biden has periodically exhibited signs of a stutter, the inability to hold on to his own train of thought, forgetting where he is and who he’s with, grossly incorrect use of language, and inappropriate behavior are not symptoms of a stutter.
