Roland Burris is the latest name being bandied about as a possible Chicago Mayoral candidate but our most recent Illinois poll suggests he wouldn't be a formidable candidate there. 35% of voters in the city approved of the job he was doing as a Senator while 37% disapproved.
Certainly those are a lot better than his overall statewide numbers where only 18% of voters approved of him and 57% disapproved. But those are still pretty bad for a sitting Democratic Senator in an overwhelmingly Democratic city. For sake of comparison Dick Durbin's approval in the city was a 62/28 spread.
My guess is that Burris' best possible outcome as a Mayoral candidate would be making a runoff and getting blown out in it.
