Ald. Jason Ervin (28) is the latest and final alderman to be absolved of having to face a challenger as he runs for a fourth full term. 

The Chicago Electoral Board on Friday rejected the recommendation of a hearing officer and removed 28th Ward candidate Shawn Walker from the Feb. 28 ballot on the basis that he did not have enough valid petition signatures. Two other candidates — Beverly Miles and Timothy Gladney — who had hoped to challenge Ervin were removed or withdrew from the ballot earlier this election season.
