Mayor Rahm Emanuel is relying on a core group of loyal campaign contributors to fund his re-election bid, including dozens of companies, firms and individuals who helped bring him to office with donations four years ago and who have since received a benefit from his administration. That can range from city approval for development projects to city contracts to mayoral endorsements or appointments. This select group of donors, who gave at least $10,000 before Emanuel was elected in 2011 and at least $10,000 since, includes individuals, spouses, business partners and companies themselves. These totals reflect donations from October 2010 through Dec. 31, 2014. (Read responses by some of the donors.)
