After last week’s citywide election, much was made of the fact that several City Council incumbents had been ousted—in some cases quite unceremoniously—from their posts. (Maria Hadden, for instance, defeated Joe Moore by twenty-seven percent in the northernmost 49th Ward.) On the South Side, however, sitting aldermen fared a little better. Most of those who will go to a runoff, like Leslie Hairston (5th) and Raymond Lopez (15th), look as if they’ll win comfortably in the April follow-up election; in fact, only Toni Foulkes (16th) trailed a challenger in the initial round of voting. But despite relatively successful end results, even some long-time aldermen only scraped through to reelection by the skin of their teeth. Here, the Weekly analyzes four close races in which the incumbent prevailed.
