By Michael Cavna, The Washington Post There’s a trick to satirizing Joe Biden: You need only look within. So says Jason Sudeikis, who starred on “Saturday Night Live” from 2005 to 2013. To create his impersonation, he zeroed in on one trait: “He feels like a people person.” The actor grew up around that friendly nature back in Kansas and simply had to channel “the outgoingness and gregariousness of my father.” The Onion writer Chad Nackers tapped his own background to create a different kind of satiric Biden — a popular “Diamond Joe” character who loves his muscle cars, motorcycles and hair-metal music.
