Incumbent Michele Smith of the 43rd Ward is on top of Caroline Vickery, also by 86 votes.

The tightest content remains the 10th Ward, where challenger Susan Sadlowski Garza holds a 33 vote lead over incumbent Alderman John Pope.

Pope’s campaign had a heavy emphasis on absentee votes and that contest could come down to 42 absentee votes that were rejected.

The campaign is challenging the rejections. In one case, the signature was found not to have matched, but Pope’s campaign says that is because the voter had a stroke and his signature no longer looks the same.
