Quinn was elected to a full term in a very close race, defeating Brady by only about 32,000 votes with Brady carrying 98 of the state's 102 counties.[3] Prior to the general election, the primary election in February 2010 featured extremely close races between candidates for the two largest parties' nominations. Quinn warded off a challenge by Comptroller Dan Hynes by a margin of about 8,300 votes, while Brady won the Republican nomination on the strength of fewer than 200 votes in a fractured seven-way race. This was the first time Gallatin County went Republican for the governor level since 1920. The election marked the first time since 1852 that the Democrats won three consecutive gubernatorial elections in Illinois.[4] This is also the first gubernatorial election since 1990 in which the winner was of the same party as the incumbent president.
