I was talking with a veteran elected official the other day who was of two minds about the prospect of anyone running against Mayor Rahm Emanuel in 2015.

First and foremost, he argued that somebody should take on Emanuel: It would be unhealthy for our world-class city if the mayor strolled to a second term without a competitive opponent, especially since his plan to close schools, on top of other cuts in working-class neighborhoods, has riled up large portions of the city. As the ancient proverb says, you can’t beat somebody with nobody. And if anybody’s going to do it, it’s time to start gearing up.

On the other hand—

“If you put your dick on the table, they’ll cut it off.”

Figuratively speaking, of course.
