Midterm elections Tuesday altered the power balance in Springfield and Washington.

It was a night that included Illinois voters pushing out incumbent Republican Gov. Bruce Rauner in favor of billionaire Democrat J.B. Pritzker and electing Lauren Underwood and Sean Casten to help give Democrats power in the U.S. House.

Here’s a look at how some of McHenry County’s biggest cities voted in the night’s biggest races:


Results at polling places in the 30 precincts covering McHenry showed politics is far from a perfect science.

Rauner’s concession came less than an hour after polls closed Tuesday, when early vote totals had Pritzker holding about 65 percent of the vote.

In McHenry, Rauner captured an overwhelming 23 of 30 precincts.

Results at the same precincts influenced the 14th Congressional race between Underwood and Republican incumbent U.S. Rep. Randy Hultgren. Vote totals showed the congressional race was much closer than the governor’s race.

Hultgren and Underwood each captured 15 precincts, but the incumbent’s 7,360 votes edged the challenger’s 7,063 – a margin of fewer than 300 ballots.

With 100 percent of McHenry County precincts reporting, Hultgren received 33,247 votes, or about 51.5 percent of the total county vote, to Underwood’s 31,303, according to unofficial results.

Crystal Lake

Hultgren beat Underwood in Crystal Lake, capturing 16 of the 26 precincts in the city that are included in the 14th Congressional District.

In his victorious 6th Congressional District race against incumbent Republican U.S. Rep. Peter Roskam, Downers Grove businessman Sean Casten won 17 of 22 Crystal Lake precincts.

McHenry County voters gave 52.4 percent of their vote to Casten, with 26,529 people who voted, according to unofficial results.

In all of Algonquin Township, which covers parts of Crystal Lake, Rauner won 44 of 68 precincts.


Rauner beat Pritzker in Woodstock, and won 16 of 29 precincts covering the city, but fellow Republican Hultgren did not fare as well.

Underwood took 14 precincts to Hultgren’s seven, outpacing her opponent 2-to-1.
