Democratic governor candidate Dan Hynes will make "an important announcement" about his campaign Thursday morning, his campaign said Wednesday night.
With 99.4 percent of the votes counted, neither Democrats nor Republicans are prepared to announce a nominee for governor.
Incredibly slim margins separate Gov. Pat Quinn from Hynes on the Democratic side and state Sens. Kirk Dillard and Bill Brady among Republicans.
President Obama called both candidates, but congratulated Quinn on the win. The Hynes camp says Obama did not ask him to concede, but the twin calls are a not-so-subtle hint that the president doesn't want this primary battle to continue into the general election.
Mayor Daley called for unity, but hedged on asking Hynes to concede.
On the GOP side, Bill Brady clings to a 509 vote lead over Kirk Dillard. Brady gained 39 votes today, while Dillard picked up 115 for a net of 73.
The races for governor aren't the only ones that are still up in the air.
In the GOP Lt. Gov primary, Jason Plummer leads Matt Murphy by 4,976 votes.
The razor-thin margins could lead to unprecedented recounts for a state with no automatic provisions for them.
The only major stalled race to conclude Wednesday was the Dem. Comptroller primary; Raja Krishnamoorthi conceded to David Miller shortly after 9 p.m.
