Democrats picked up three seats Republicans previously held in the Will County Board on Tuesday night.
Republican Judy Ogalla and Democrat Laurie Summers will again represent Will County District 1 residents.
Will County Board Speaker Jim Moustis and Democrat Amanda Koch were chosen to represent District 2, defeating Republican Keith Ogle.
Koch was a political newcomer and U.S. Army veteran who did two tours of duty in the Middle East. Ogle beat incumbent Cory Singer for the second Republican nomination back in March.
In a solidly blue district, Democrats Jackie Traynere and Kenneth Harris ran unopposed.
Republican Gretchen Fritz was re-elected and Democrat Meta Mueller defeated incumbent Republican Darren Bennefield by more than 2,500 votes.
Republican Don Gould was re-elected, while Democrat Joe Van Duyne defeated incumbent Republican Debbie Militello. Van Duyne and Gould both separated themselves by opposing the controversial Compass Business Park.
Both Republicans Stephen Balich and Mike Fricilone were re-elected, defeating Democratic newcomer Kyle Killacky. Fricilone edged Killacky out by only 602 votes.
Fricilone and Balich campaigned as a pair.
Republican Annette Parker was re-elected, and Democrat Rachel Ventura defeated Democrat Jim Murphy, filling the vacant seat Will County Clerk-elect Lauren Staley-Ferry left behind.
Republican Julie Anne Berkowicz and Democrat Michelle “Mimi” Cowan defeated Republican Kathy Havel and Democrat Jim Kopchok.
Havel and Berkowicz did the unlikely in March and beat both Republican incumbents Chuck Maher and Suzanne Hart.
