Chicago holds its nonpartisan city elections on February 24, 2015. Voters elect three citywide offices: Mayor, City Clerk, and Treasurer. For the latter two offices, only one candidate will be listed on the ballot. Candidates for the citywide offices need 12,500 valid signatures, and that is so severe, there is very little competition for the two lesser offices. Two candidates for city clerk filed petitions, but one candidate’s petition was challenged and the challenger prevailed.

Here is the long list of candidates for Alderman who were challenged, and what the results of each challenge were. The document contains 16 pages. There are races for Alderman in 50 districts. Not all of the challenges have been adjudicated yet. At this point it is not known how many candidates will be on for Mayor.
