"My mother believed and my father believed that if I wanted to be President of the United States, I could be, I could be Vice President!" said Vice President Joe Biden. [source]Here, ex-vice president Biden blandly adopts an opinion and immediately refuses to justify his decision:
Biden Gave A Lengthy Endorsement Of Kavanaugh Accuser Until One Question Caused Him To Walk Away | The Daily Caller: Former Vice President Joe Biden emphatically supported Kavanaugh accuser Dr. Christine Blasey Ford Monday night, faltering only when a reporter asked him about the credibility of a claim made over 35 years ago. “What I’m going to do is I’m not going to answer any more questions,” Biden said, deflecting a reporter’s question asking whether it was significant that the assault claim refers to an incident that allegedly occurred when Supreme Court nominee Brett Kavanaugh was 17 years old. “I’d be happy to talk about Ireland,” Biden added during his remarks to a group of reporters at Irish ambassador to the U.S. Dan Mulhall’s residence.(But he's a master at changing the subject when asked questions which would require him to think.)
Perhaps Biden's most important contribution to American Society is that he provides material for late-night talk-show hosts.
