Roger Kimball argues that #JoeBiden's cognitive decline and limited work schedule, likened to a "10 a.m. to 4 p.m." president, jeopardize the #US's stability and global standing. He criticizes the Democrats for perpetuating an illusion of Biden's competence and suggests invoking the #TwentyFifthAmendment due to Biden's perceived inability to effectively perform presidential duties, warning of potential instability with #KamalaHarris as a successor.
