The race for Illinois’ 8th congressional district remains tight nearly a week after Election Day. It could still be awhile before the results come in.

Republican congressional candidate Joe Walsh has about a 350-vote lead over incumbent Democratic Representative Melissa Bean. Walsh declared victory when he held a slightly bigger lead, last week, but Bean hasn’t conceded.  She’s said she wants all the votes to be counted.

The 8th congressional district is divided up in parts of Lake, McHenry and Cook counties. Cook County election officials have counted some absentee and provisional ballots, but they’re still waiting on just over 690 ballots that might be mailed in during the coming week. Lake and McHenry counties have together received hundreds of mail-in ballots, but election officials say they won’t begin counting until the mail-in deadline of November 16. They say they’re waiting for the deadline in order to protect the anonymity of voters.
