Chicago Votes for Mayor, Obama Advisor Leads Polls VOA News February 22, 2011 Chicago mayoral candidate Rahm Emanuel (file) Photo: AP Chicago mayoral candidate Rahm Emanuel (file) Residents of Chicago, the third-largest city in the United States, are voting Tuesday for a new mayor, with a key advisor to U.S. President Barack Obama leading in pre-election polls. Rahm Emanuel, who was Mr. Obama's chief of staff until he resigned last fall to run for Chicago mayor, has held a commanding lead in polls and campaign fundraising leading up to Tuesday's voting. Emanuel or another candidate must win more than half the vote in the Midwestern city or face a runoff election April 5 against the second-place finisher. Also in the race are Carol Moseley Braun, the first African American woman elected as a U.S. senator, former Chicago school board president Gery Chico and City Clerk Miguel del Valle. Mr. Obama has endorsed the 51-year-old Emanuel, as has former U.S. President Bill Clinton, for whom Emanuel was a senior advisor in the 1990s. Emanuel, known as "Rahmbo" for his blunt and often foul-mouthed way of speaking, quickly became the favorite to succeed long-time Chicago Mayor Richard Daley when he left Washington to return to his native city. Emanuel's political opponents tried to keep him off the ballot since he had not met a city requirement to live in Chicago in the year preceding the election. A court decision briefly threw him off the ballot, but the Illinois Supreme Court reinstated his name. Emanuel has often said his dream was to become Chicago's mayor. One pre-election poll showed him with the support of 58 percent of those surveyed, with his opponents trailing far behind. Whoever wins the election faces daunting city financial woes. Like many local and state governments in the United States, Chicago faces a huge cash shortfall in its 2011 budget, more than $600 million. The city also has not funded an estimated $20 billion it owes to retired municipal workers. .
