One of Milwaukee County's longest-serving county supervisors lost his election battle Tuesday after being redistricted into a new seat, and a former state legislator who faced sexual misconduct allegations appeared to have lost in a nail-biter in his bid to gain a seat on the board.

One district race was left uncalled, pending a final count of the ballots.

More than half of the 18 races for board seats went unchallenged in an election night that resulted in potentially six new faces joining the board.

John F. Weishan Jr., who sought reelection in the newly formed minority-majority District 15, was ousted by Peter M. Burgelis, a newcomer to the Milwaukee political scene. Weishan has sat on the board since 2000. 

Burgelis won in a landslide victory against Weishan.

"I am the first out member of the LGBTQ community elected to the Milwaukee County Board of Supervisors," Burgelis told the Milwaukee Journal Sentinel. "It's a historic win tonight — not just for the LGBTQ community, but for Milwaukee County as a whole."

"We're ready for tomorrow — Day One," he said.

Weishan was one of the six supervisors displaced from their former districts by the new district lines outlined by the redistricting process that was finalized earlier this year.

Hispanic candidate Juan Miguel Martinez, a union organizer and freelance independent journalist, held a narrow 17 vote margin over his opponent, former state Rep. Josh Zepnick, to win District 12 — one of Milwaukee's two Latino-majority districts.

"This was less a win for me and more of a win for the people," Martinez said. "I'm very proud to represent a district that I've called home in a city that I've known for my entire life."

Late Tuesday night Zepnick said that he was trying to determine whether to ask for a recount. Martinez said he would not contest if Zepnick files for a recount. 

Milwaukee County Clerk George Christenson said Zepnick can request a recount because he trailed by less than 40 votes. But under state law he would have to pay for the recount as the difference was greater than 10 votes.

In a recent interview with the Milwaukee Journal Sentinel, Zepnick had asked voters to trust that he's changed since being accused of sexual misconduct.

Dyango Josés Zerpa, a legislative aide to Milwaukee County Supervisor Sylvia Ortiz-Velez, was elected to District 14 supervisor. Kathleen Vincent was elected to District 11.

According to unofficial final results, a dozen incumbent supervisors cruised through the election, including District 1's Liz Sumner, District 2's Willie Johnson Jr., District 3's Sheldon A. Wasserman, and District 9's Patti Logsdon.    

Former District 9 county supervisor and former Franklin Ald. Steve F. Taylor was also elected — unopposed — as the new District 17 supervisor.

Among the many issues the board contended with during the last two years, including the once-a-decade redistricting process and a failed independent redistricting committee, none suspected a write-in only ballot for District 18.

With a week before the countywide race, eight people registered as write-in candidates for the district, with its incumbent Sup. Russell Antonio Goodwin Sr. and a former supervisor, Deanna Alexander, in the mix.

But election day saw no declared winner.

Christenson said the county will have to do a hand count for the district and it will likely take several days to get the final result.

Having followed local politics since the mid-1970s, Mordecai Lee,  an emeritus political science professor at UW-Milwaukee, said he was astonished by the situation in District 18.

"This is astonishing that there's no candidate on the ballot for an elected office," said Lee the day before Election Day. "Sometimes this happens in a town or a village — but a county board district in the most populous county in the state, it's hard to believe that it's there for the taking."

"I don't recall this ever happening in Milwaukee County," Lee added.

Goodwin was six signatures short of the 200 required to get on the District 18 ballot after filing his nomination signatures by the  Milwaukee County Election Jan. 4 deadline.
