John Keen, Tim Walsh, Laura Hruska and, apparently, Garry Gryczan won seats on the Riverside-Brookfield High School District 208 board Tuesday. Keen led the field of seven candidates with all 28 precincts reporting, and Tim Walsh and Laura Hruska were also winners.

But the real excitement was the close battle between Gryczan and Tom Powers for the fourth and final seat up for election Tuesday.

With all 28 precincts reporting Gryczan unofficially edged out Powers for the last seat of the board by just 64 votes. Gryczan finished the night with 3,065 votes compared to 3,001 votes for Powers.

However, some absentee ballots may still have to be counted, so the results are not yet official and could change.

Keen was the top vote-getter with 3,728 votes, followed by Walsh with 3,172 votes and Hruska with 3,149 votes.

Trailing the field were the two candidates from North Riverside. Lenora Giurini finished in sixth place with 2,341 votes and Lou Surprenant trailed the field with 1,577 votes.

The four winners will replace four incumbents, who all chose not to run again.

Keen, a radiologist at Stroger Hospital, and Gryczan ran as a team. They were backed by the three District 208 board members elected two years ago, Dan Moon, Matt Snide and Mike Welch.

Keen and Gryczan were also backed by Jerry Buttimer and Chris Robling, who also supported Moon, Sinde and Welch two years ago.

Keen grew up in Riverside, is a graduate of RB and now lives in Brookfield, which may have enabled him to earn support throughout the district.

Tuesday night Keen said the big story of the night was the defeat of the RB tax referendum.

“I think you have to put it in context of the referendum vote, because I think that’s the overwhelming message,” said Keen who didn’t take a public position for or against the referendum during the campaign.

“Speaking honestly as an alumnus of the school I’m really sad,” Keen said. “You know, I’m sad that the community voted the way it did in a resounding fashion. It also says, those results, speaking as physician, means we’ve got to do major surgery on that school in order to rebuild the trust of the voters.”

Keen and Gryczan ran by far the most aggressive campaign of the seven candidates. Both of them went out every Saturday for a little more than two months, ringing doorbells throughout the district to introduce themselves to voters.

Their campaign also mailed oversized postcards to many voters, highlighting their qualifications and touting their endorsement from Moon, Sinde and Welch. They ran on a platform emphasizing integrity and fiscal responsibility, and neither took a position on the referendum.

Gryczan said late Tuesday night that he thought the shoe-leather campaigning he and Keen did made the difference in the tight race for fourth.

“I think it was the fact that we were out there going door to door, meeting people, listening to them, getting our name out there,” Gryczan said. “We had hit every community – Brookfield, North Riverside and Riverside.”

Powers, who currently serves on the District 95 school board, took a totally different approach to the campaign, appearing in two candidate forums and doing newspaper endorsement interviews but eschewing other forms of campaigning.

“I did not go door to door, I did not put up signs,” Powers said on Monday. “Campaigning just doesn’t feel right. I know it’s absolutely acceptable. Don’t get me wrong, I know it’s acceptable, but this is not supposed to be an agenda-driven position.”

Walsh seemed to benefit from a strong turnout in his hometown of Riverside.

Hruska served on the RB school board from 2005 until 2009, but lost her bid for reelection two years ago. This time she bounced back. She was the only school board candidate to come out against the RB tax referendum, which lost overwhelmingly. Her public position against the referendum may have helped her with many voters.

She also appeared to benefit from her reputation as a fiscal watchdog or, some would say, tightwad. Three years ago while on the school board, Hruska cast the only vote against the current teachers’ contract.
