Dubbed "City Hall's new No. 1 lobbyist" by the Sun-Times, Kasper, who doubles as an election lawyer, has seen his clout multiply since a client became mayor (he argued Rahm's residency case). Not that he didn't have sway before: As the former general counsel to Mike Madigan (No. 2), he was big man on campus in Springfield.
