My buddy Ben Cal­houn put together a great story for WBEZ on why Obama’s polit­i­cal suc­cess has had every­thing to do with choos­ing Hyde Park as his Chicago home. It does a nice job of answer­ing one of the key ques­tions left open by James Merriner’s “Friends of O,” (Chicago Mag­a­zine) and Andrew Ferguson’s “Mr. Obama’s Neighborhood” (The Weekly Standard).
