Rahm Begins Polling to Test Mayoral Run Obama chief of staff also gets his Chicago pals involved By Nick McMaster, Newser Staff Posted Sep 14, 2010 5:15 PM CDT 7 comments Comments In this April 27, 2010 file photo, White House Chief of Staff Rahm Emanuel laughs as he takes some good natured ribbing while participating in the sixth annual Global Cities Forum in Chicago. (AP Photo/M. Spencer Green, File) (Newser) – Rahm Emanuel is taking his first tangible steps toward an expected run for the Chicago mayor's seat. His longtime pollster has begun surveying city residents, reports Lynn Sweet of the Chicago Sun-Times. "Sources told me that polling calls for Emanuel were being made over the weekend and that Emanuel has activated his Chicago network of pals to reach out to political figures in Chicago on his behalf." She also expects him to visit the city by the end of the month. Emanuel is popular in Chicago but faces uncertain prospects among the city's large African-American population—despite his deep connections to Barack Obama. And the already crowded field of contenders appears to be adding a familiar face: Carol Moseley Braun. She was the first black female senator from Illinois but has been out of politics since 2004.
