Mayor Richard M. Daley of Chicago has publicly backed Barack Obama in his bid for the Democratic Nomination.
The Daley family has a long relationship with the Clinton family, so whilst this wouldn't have been easy to break to Hillary, one also wouldn't expect Daley to do anything other than support his own state's Senator.
Mayor Daley said that he has spoken to Hillary Clinton and said that she understands why he made the decision to support Obama.
Daley has said that Obama has the best chance to turn around a dysfunctional government.
Former Commerce Secretary in the Clinton Administration and brother of the Mayor, Bill Daley will also be supporting Obama's bid for the nomination.
