Supporters erupted. His mother burst into tears. His sister shouted. Mark Kleinschmidt just smiled contently, arms crossed but giving the kind of ear-to-ear grin you could feel across the room, satisfaction and disbelief merging together on his face. The campaign had just received word that rival Matt Czajkowski had made his concession speech at the Franklin Hotel.

The progressive bloc had won. They’d just escaped a new, moderate business-centered group gaining traction and council seats. Not so fast.

Word came back that one precinct, Patterson, was yet to report. Kleinschmidt was up a scant 168 votes. The jubilation turned to shocked concern. It was too close to call.

“I don’t want a ‘Dewey defeats Truman’ headline,” Kleinschmidt warned reporters at his R&R Grill party. The pack of local politicos returned to the laptop, clicking refresh again and again.

Moments later, the candidate’s ever-buzzing cell phone went off once more. It was Mayor Kevin Foy calling to congratulate him.

Kleinschmidt cautioned him, but thanked him for his support. Then the results flashed on the TV screens. It was final — Kleinschmidt had won.

“Oh, that’s it. We won it,” he said calmly to Foy. The crowd, already snakebitten, didn’t know what to do for a moment. Then it erupted again.

“There’s a lot of people with cameras here, and I’m going to talk to them,” Kleinschmidt told his sudden predecessor.

The swarm of reporters surged forward, someone handed the new mayor a microphone. With the other Triangle races not as contested, media came to Chapel Hill in search of a story. Lights flashed.

Kleinschmidt’s back looked like a Christmas tree with microphones from four different TV stations hooked up to him, wires interwoven.

“How does this affect my silhoutte,” he asked jokingly. “That’s the issue that the gay mayor is concerned about.”

It was his first chance to breathe. The first time he could make light of what had been a heated race that drew closer than most had anticipated as the campaign wore on. He’d done it. The boy who moved from place to place during his youth and who dreamed of attending UNC since he was 9 years old not only had a home, he had the support needed to lead it.

He gave an eloquent and pointed speech. Realizing the close margin, he thanked everyone in the room for making the result reality. “The work of any one one person is significant,” he told them. Understanding that he’d still have to work with Czajkowski, he thanked him for a competitive race and for serving “in a way no other council member could.”

Also clear was that the race brought to the surface an underlying split in philosophy in town politics, Czajkowski supporters being far more in number than most had realized. Kleinschmidt made clear his intentions to mend the wounds.

A cake was rolled out, drinks flowed. Buoying the mood were the council results. Laurin Easthom and Ed Harrison kept their seats. Newcomers Penny Rich, a voter-owned candidate, and Gene Pease also were victorious. Rich, Easthom and Harrison all were at Kleinschmidt’s party, posing for pictures and thanking supporters.

I waded through a veritable who’s who of local politics (at one point there were enough county commissioners there to hold a meeting), all coming to offer their congratulations. Also there was competitor Augustus Cho, who came to shake Kleinschmidt’s hand. What follows is a list of who I talked to and what I gleaned:

Michelle Kleinschmidt Hoover, Mark’s twin sister and campaign treasurer:

This marked her third successful campaign having worked on Mark’s initial run for council in 2001 and on Cam Hill’s victorious effort in 2003 for that same office. She, like her twin, was exuding happiness and relief.

“It’s amazing. I’m so proud of him. I’m glad he’s doing the political thing,” she said, noting that she could hardly bear the supsense. She couldn’t even eat until the results were in.

“He has spent so much time and hard work in this campaign. It’s been day and night for him.”

Penny Rich, the leading vote-getter in the council race, and along with Kleinschimdt, the only voter-owned elections candidate

Rich said she was disappointed when the Public Policy Polling survey released Monday showed her in sixth, but she knew she had more support than that.

“It didn’t seem right,” she said. “I thought it was a little off.”

It sure was. Rich not only won, she was the only candidate to earn more than 4,000 votes. After finishing in sixth in 2007, the second time worked for Rich.

She was quick to credit the voter owned elections pilot program, having said before that she felt she needed to win to validate it.

“It really worked. … It got everyone involved because of those $5 and $10 checks. Now it’s time to get down to business.”

Rich, a personal chef, had been watching the returns as home, cooking a pot of chili to calm her nerves.

Mayor Kevin Foy

Foy endorsed Kleinschmidt and the old colleagues shared an embrace when he arrived.

“I couldn’t be happier for him. He’s going to make an excellent mayor,” he said.

“He’s in a perfect position to change things and also keep things moving in the right direction.”

Foy said the success of Kleinschimdt and Rich shows that the voter-owned process worked and that he hopes future candidates will examine this election as a case study.

“Penny just swamped her opponents,” he said.

With the Dec. 7 inauguration now drawing near, Foy can start charting his next course. Mayor Pro Tem Jim Ward even greeted him by saying, “Hey, lame duck.”

Marge Kleinschmidt, Mark’s mother

Drained from the night but bubbling with joy, Kleinschmidt couldn’t hide how proud she was of her son.

“I just can’t stand it,” she said.

We talked about Mark’s journey to Chapel Hill, which she said started at age 9.

“He said he wanted to go to UNC, but he worried what we’d do if he didn’t get a scholarship,” she said. “I said, ‘If you want to go to UNC, I’ll scrub toilets to get you there.’”

He got there via scholarship, and he’s really arrived now.

“He’s been a part of Chapel Hill ever since,” she said. “He’s a wonderful person, and I’m not just saying that because I’m his mom.”

Tom Jensen, communications director of Public Policy Polling

Short of Rich’s victory and the fact that Gene Pease and Laurin Easthom finished 4th and 3rd instead of 3rd and 4th, respectively, Jensen’s poll was spot on. It was the first such poll conducted in Chapel Hill, and he was worried that the small sample size might hinder its accuracy. In the end, it all worked out.

“All the things we would have assumed to be true we now have data showing they are true,” he said, noting that Foy supporters voted for Kleinschimdt and detractors went to Czajkowski.

The main takeaway, though, is that given the final results, Kleinschmidt now needs to work to unite a divided community, Jensen said.

“We really are a 50-50 community on whether things are good or not right now,” he said.

That’s the charge for tomorrow. As for Election Day, all seemed right at R&R Grill.
