The Onion has a lot of fun portraying Joe Biden as a free spirit whose working class roots and uncensored attitude clash comically with peoples' concept of groomed, self-preserving politicians. The political right casts him as an idiot, and mainstream media coverage comments on his penchant for "gaffes", but The Onion writers heroize Biden through their satire.
The Onion writers (and, by extension, members of their audience) who love Biden value in him a rebellious streak, his individuality, and his "authenticity" or sincerity, all of which is located in his being uncensored (Biden says what Biden thinks when Biden wants). The justification behind this reverence, however, lies in his being powerful and famous. Ordinarily, The Onion would mock disdainfully a blue collar, working class white who might wash his Trans Am shirtless in the driveway or resort to hitchhiking for transportation. Such a character would be portrayed as too dumb to know which party to vote for or what music to listen to or shows to watch on TV. His wife might even enter their white trash daughter in a child beauty pageant.
Notes:
- Biden, of course, is more competent and astute than one might think after reading about him, and The Onion writers and their audience knows this, which is why the satire works in two ways: it taps into (1) our concept of politicians and (2) our experience with press coverage of Biden.
