When Hillary Clinton wants you to think "she's just like you," she busts out her southern revival accent or eats at Chipotle. When Obama wanted you to think he was just a "regular fella" he'd get a burger and beer that his wife supposedly disapproved of. Virtually every out-of-touch politician has some contrived way of trying to make it seem that they're just one of the down-to-Earth "real people" they hope to rule with an iron fist.
Joe Biden has two such crutches.
