That was a quick transition: Former White House Chief of Staff Rahm Emanuel, who marked his last day in the Obama administration on Friday, officially announced his candidacy for the mayorship of Chicago on Sunday. Emanuel posted a video on his new campaign site that outlines the major issues he’ll be focusing on in his bid, specifically listing education reform, crime-reduction efforts, and job creation. He also announced a listening tour across the city. “I’m calling this the ‘Tell It Like It Is’ tour, because I want to hear from you in blunt terms,” he said. Emanuel would succeed longtime mayor Richard M. Daley, who is retiring this year; the Democratic primary is in February.
