Thursday's debate was an unmitigated disaster for Democrats. For perhaps the first time on a national debate stage, former President Donald Trump seemed relatively calm and articulate. In contrast, President Joe Biden was doddering, incoherent, and often seemed unable to string an intelligible sentence together.
While questions surrounding Biden's cognitive abilities have already defined the 81-year-old president's campaign, any plausible deniability about his mental acuity was effectively destroyed by his abysmal performance on Thursday.
