Joe Biden is only fully functional from 10 a.m. to 4 p.m., according to a report by Axios published Saturday in the wake of Biden’s disastrous not-ready-for-primetime debate with President Trump Thursday night. The report states White House staff know there are ‘two Bidens’: One who is fully engaged for about six hours a day and the one Americans (and the world) saw staring into space and struggling to articulate lucid, complete thoughts during the debate Thursday night.
