New York City Mayor Rudy Giuliani embraces mayoral candidate Mike Bloomberg at a press conference on the steps of City Hall in New York in this October 27, 2001 file photo. Had it not been for the Sept. 11 attacks, neither Giuliani nor Bloomberg would have such high profiles on the American political stage. If Giuliani is always remembered as the 9/11 mayor of New York City for his leadership in the days of fear that followed, then Bloomberg will be recalled as the mayor who cajoled New Yorkers to focus on the future after the worst tragedy in their history.
