The question must be posed: does defending democracy still mean supporting Joe Biden?
And the simplest answer must immediately be proffered: yes, if Joe Biden is the Democratic presidential candidate in November, then defending democracy means vigorously supporting him.
But November is many months away, and a lot can change between now and then. And at the same time, at least one thing has not changed: Biden’s poll numbers are weak, Biden’s candidacy seems extremely vulnerable, and Biden’s advanced age is becoming an increasingly important liability, because of the way opponents have successfully framed it, but also because of his own performance, as an elderly man who lacks the physical and mental vigor that many Americans reasonably associate with the job of President of the United States.
