 From 10 a.m. to 4 p.m., Biden is dependably engaged. Many of his public events are held within those hours. Outside that time range or while traveling abroad, Biden is more likely to have verbal miscues and become fatigued, unquote. So he's like a reverse vampire. He's only good in the sunlight. He's like a zombie vampire, alive, then dead, then quasi-alive, but only during the day. It's like Night of the Living Dead.
