Under Emanuel, the city attracted major employers, experienced a building boom and boosted tourism. He bolstered O’Hare and Midway airports and kept a shine on downtown, the lakefront and many neighborhoods. He made little progress helping the underdeveloped South and West sides, besides recruiting the oft-mentioned Whole Foods to Englewood. Yes, he got the Barack Obama Presidential Center for Jackson Park, but that was a gimme — imagine the scandal if Obama had taken his library to New York. Will Emanuel cap his tenure by winning Amazon’s second headquarters? We’ll know soon.
