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).
Like so many politicians before him, Emanuel has taken many steps to present himself as a man of the people. It is a longtime tradition for politicians to sacrifice a little bit of dignity to do things like eat a pork chop on a stick at the county fair. But it's a careful balancing act, and, as the 2014 midterm campaigns get going, candidates can learn something from Emanuel's example of what can happen when one errs on the dignity-sacrificing side. It looks like Emanuel is standing next to an aide, because he leans over and says something in his ear. We do not know who the woman is.
He never took off his sunglasses, because sunglasses are cool, just like Rahm Emanuel.
The former ballet dancer has been spotted dancing in public before. At the 2012 Taste of Chicago, he was taped dancing to Jennifer Hudson. The mayor was doing more of a shoulder sway thing than hip thrusts.
