This was an extraordinary evening.

Joe Biden‘s debate performance was among the worst by any presidential candidate in history, if not the worst.

It was an “unmitigated disaster”, “a meltdown”, and “a slow-motion car crash”.

Those are not descriptors from Republican voters, they are the words of Democrats. Even former aides of President Biden admit it was a really horrible night for him.

Team Biden hoped to see State of the Union Joe on the stage, when the president gave a slick, impassioned and well-delivered speech.
