Voters in the 26th Senate District on Nov. 6 will weigh in on the only contested Illinois Senate race in McHenry County.

Democratic candidate Amanda Howland is challenging Republican incumbent Dan Duffy for the seat. Under post-census redistricting, the 26th District’s boundaries in McHenry County shift south to cover Cary, Fox River Grove, eastern Algonquin, Lake in the Hills and Crystal Lake, as well as parts of Lake, Kane and Cook counties.

Candidates for the 32nd and 33rd Senate districts covering the remainder of the county – Republican incumbent Pam Althoff and newcomer Karen McConnaughay – are running unopposed. All 59 seats in the Senate are up for election because of redistricting.
