The results are still coming in, but the race has been called. Former congressman and former White House chief of staff Rahm Emanuel will be the next mayor of Chicago.
With 97 percent of precincts counted, Emanuel had won 55.1 percent to 24.2 percent for Gery Chico, his next closest competitor.
Emanuel needed a final result of more than 50 percent to forestall a runoff election in April.
"Thank you Chicago! Your hard work & support got us here. Looking forward to working together as your next mayor," Emanuel tweeted around ten minutes after 9 p.m. Eastern.
