Too old and senile to prosecute, apparently, and yet Democrats will spend the next year arguing that Biden has the physical stamina and mental acuity to serve another four years as president.

The reality of Biden’s mental decline should be frightening to all Americans, no matter what anybody feels about President Trump. It is recklessly irresponsible for Biden and those surrounding him to allow him to seek reelection, and as they are unlikely to budge, these revelations, backed up by what everybody is witnessing in his public appearances, should trigger serious conversations among Democrats about how to begin the messy process of replacing him as nominee.
