From the New Yorker, Ron Regan addresses comparisons between him and Rahm Emanuel (both former dancers):
I’m a well-known actor – not a big star, but I appear in movies – and you’re talking about someone who was in the drama club in high school.” He argued that dancing and politics are “really two different parts of your brain.” He said, “Politics is the art of compromise. It’s shades of gray and nuance. There’s nowhere to hide when you’re a dancer. You’re almost literally naked, wearing an outfit that reveals everything about you.” He went on, “There are no Sarah Palins in dance – no one who doesn’t know what they’re doing. They’re weeded out by the time you get to be a professional.”
Reagan is profoundly wrong; people are weeded out of politics, just not by qualities we’d like.
