CHICAGO (AP) — A longtime suburban Chicago mayor who held a fundraiser for President Donald Trump last year has expanded his narrow lead in his re-election battle with a union organizer backed by top Democrats.

With all precincts reporting Wednesday, Bolingbrook Mayor Roger Claar held a 104-vote lead over Will County Commissioner Jackie Traynere. The vote tally will be made official April 25 after the vote by mail ballots postmarked by April 4 and provisional ballots are counted. The county clerk's office said there are no more than about 400 of those votes to be counted, and Traynere spokesman Tom Bowen did not hold out much hope she could overtake Claar.

"It's an uphill climb," he said. "Jackie has called Roger to congratulate him."

Still, after supporting Trump, a 104-vote lead in a race in which about 12,500 votes were cast was a far different experience for a mayor who has been in office since 1986 and whose last three elections came after running unopposed or against write-in candidates.
