Democrat Susana Mendoza has won the Illinois comptroller's special election over Republican incumbent Leslie Munger.
Mendoza, a former state legislator, is Chicago's city clerk. She'll finish the remainder of the comptroller term, which expires in 2019.
Munger was appointed to the office, which pays the state's bills, by Gov. Bruce Rauner last year after Judy Baar Topinka's 2014 death.
The big-money special election coincided with the presidential contest, thrusting the usually low-profile race into the spotlight.
Munger dominated in fundraising, due to a combined $5 million from two businessmen with ties to Rauner and $2 million from the governor and his campaign fund. About $3 million was transferred to the Illinois GOP for legislative races.
The other candidates were Libertarian Claire Ball of Addison and Green Party candidate Tim Curtin of Hillside.
