9:27 p.m.: And the AP calls it.  At last.  Congrats to the whole Quigley team!

9:09 p.m.: Fox Chicago's Jack Conaty just reported that both Fritchey and Feigenholtz have called Quigley to concede.

9:03 p.m.: The Quigley campaign just sent out a press release describing their lead as "virtually insurmountable," which it certainly appears to be.  Using our fundraising tracker, they also estimated that Quigley was outspent five-to-one by his opponents in the race.

8:23 pm: With 77 percent of precincts reporting, there are 42,261 votes counted.  Quigley has 22.5 percent of this vote, followed by Fritchey with 18 percent, and Feigenholtz with 17 percent.  Looks like this thing's a done deal.

8:00 pm: ABC7 has the best vote tracker out there.  At the moment, with 73 percent of precincts reporting, Mike Quigley has opened up about a 2,000 vote lead over both Sara Feigenholtz and John Fritchey.

7:32 pm: Deep thought: The winner of tonight's Democratic primary is going to receive 11 concession calls.

The Tribune has some early results.  We'll have more in a bit.
