Slo Joe was elected to the Senate in 1972. He promptly joined the Democrat majority in undermining the new Paris Accords. South Vietnam collapsed when the US abandoned it, and Slo Joe voted for that abandonment.
Almost fifty years later, Slo Joe has done the same thing with Afghanistan. Talleyrand famously said of the Bourbons that "they had learned nothing, and forgotten nothing." Well, Slo Joe's done Talleyrand's bon mot one better. He's obviously learned nothing in almost fifty years in Washington. And he's proven you don't have to remember anything either.
