* On Wednesday I wrote about potential challengers to Mayor Rahm Emanuel and listed Cook County Board President Toni Preckwinkle as a significant challenger and Rep. Luis Gutierrez as capable of mounting a passionate campaign. A lot of people asked about Cook County Sheriff Tom Dart. I like Dart, but Dart doesn’t have a natural constituency. He may have credibility but he doesn’t have the deep roots or ethnic/racial identification of the other candidates. I say if it’s Emanuel and Dart, Rahm slaughters him.
