All of Cook County's 1,937 suburban precincts have reported results, and Gov. Pat Quinn is the county's unofficial winner.
Some precincts around the state still haven't weighed in, but with Cook County in his pocket, the incumbent just picked up some extra slack against challenger Dan Hynes.
It helps that President Barack Obama has already called Quinn to congratulate him, despite Hynes' vow to continue fighting last night.
It looks like the White House is sending a signal that it wants no more mudslinging over the Democratic nomination in Obama's home state.
Cook County Clerk David Orr's office says precinct-specific results will be available soon.
About 1 percent of precinct results are still missing around the state, which means the Democratic and Republican gubernatorial races are still in a toss-up situation.
In Cook County, GOP candidate Andy McKenna swept up more than 30 percent of the vote, but it wasn't enough to earn him the nomination statewide.
Kirk Dillard and Bill Brady lead that race with about 20 percent of the statewide vote each.
