Ditching Biden is the only way to unite two important groups of Democrats: those with some grasp of reality, who recognize that Biden is far too old to run again, and those who still have their head in the sand about the issue, but will rally around anyone who isn’t Trump.

If we stick with Biden the election is lost. This will not be the last time Biden has a poor showing in public, revealing just how hard it is for him to speak and think at his advanced age. Every time it happens, more voters pay attention, and his poll numbers will sink more.
