Alderman Ross Arnett, who just won reelection last week, is facing recall threats over his proposal to change the form of government. Arnett's plan would strip the mayor of some power, turning him into more of a city council member. This was after a Republican Mike Pantelides defeated the incumbent Democrat, Josh Cohen for the seat (though Arnett mentions this was an idea he had proposed in the past).
Petitioners would need 30% of registered voters. A replacement would be filled by either of special election or by appointment (depending on how much time is left).
