The Republican primary for DuPage County sheriff was one of the most hotly contested races on the March 20 ballot, but the results did not turn out to be that close.
With 77 percent of precincts reporting, James Mendrick was leading opponent Frank Bibbiano by about 9,000 votes, giving him about 60.1 percent of the vote versus Bibbiano's about 39.9 percent, according to unofficial results from the DuPage County Election Commission.
Mendrick will face Democrat Gregory Whalen – who did not have a primary opponent – in the November general election.
The winner will replace Sheriff John Zaruba, who is retiring at the end of the year.
Bibbiano, the undersheriff, had Zaruba’s endorsement. Mendrick, a patrol commander for the office, enjoyed the support of DuPage County Board Chairman Dan Cronin.
Mendrick, a Woodridge resident, has 16 years of supervisory experience in the Sheriff’s Office. Bibbiano, of Elmhurst, has held several positions during his 18 years with the office.
