Obama on Language

Barack Obama recently misused "nonplussed", prompting buzz about his supposed elitism.

But like the loss of a Muslim outreach director, it's hard to fit this into the bigger picture. What does it mean when he uses college words, but in the wrong sense? Is that elitist, or plebian?

Me, I'm just smart enough to use words like "nonplussed" incorrectly, so I'm starting to really identify with Barack. I just feel like he's the only candidate I could kick back and enjoy a fancy import with at some obscure microbrewery.
