Or as he calls it, dancing.

Via The Atlantic:

At last weekend’s Taste of Chicago, Chicago Mayor Rahm Emanuel danced to Robin Thicke. With hip thrusts. And it was all caught on phone. The video was posted by YouTube userjwhousto422, who does not have much of an Internet presence. (It’s his or her first video ever.) We noticed it after it was tweeted by preeminent cartoon blogger Josh Fruhlinger, who was amused that Emanuel appears to be getting intimate with a chair. He bounced along with the crowd to “Blurred Lines.” It took a minute for the mayor to get into the song, but once he did, he was feeling it so much that he took off his tie while biting his lower lip.

Taste of Chicago is a giant food and music festival held every summer in the city’s Grant Park. Put on by the city, it also gives Emanuel a chance to look cool by giving him a chance to associate himself with fun things like the band Fun. and food trucks. But like all “cool” politicians, it is a lot more difficult to look cool when the music starts.

Emanuel’s appearance at the concert, but not his dancing apparently, was noted by local blogs as a cool thing to do such as Chicago Now, which noted the mayor is a music fan and went to see Fun. His backstage meeting with Mila Kunis and Ashton Kutcher got some notice (the mayor’s tie was still on, below).
