Last Thursday was not a good day for Joe Biden. During the president’s shaky and at times incoherent debate performance, he appeared weaker and frailer in real time than the American public had ever seen.

Both his supporters and detractors have turned this yo-yoing into a talking point that has come up frequently that he “didn’t have my best debate night,” and his press secretary as the result of a cold rather than “an episode.” Indeed, earlier this year, at the State of the Union, Biden appeared much more lucid.
