Former Cambridge Commissioner Stephen Rideout defeated state Sen. Addie Eckardt on Tuesday to become the next mayor of Cambridge.

Official results for the runoff election were released at about 9 p.m., once all in-person and absentee ballots were scanned and tallied.

Rideout received 681 votes to Eckardt's 557 votes. In all, 1,238 Cambridge residents voted in the runoff.

In a six-candidate Aug. 23 special election, which the City Council called for on June 27, Rideout and Eckardt were the top vote-getters, with 35 percent and 30 percent, respectively.

Since neither received more than 50 percent of the votes, a runoff election was required.

Following a career as a Virginia juvenile-court judge, Rideout became active with various groups in Cambridge and served on the City Council from mid-2016 to January 2021. He will fulfill the unexpired term of former Mayor Andrew Bradshaw, who resigned early this year. The term runs through December 2024.

Eckardt, a 28-year General Assembly veteran who has spent the past eight years in the state Senate, entered the mayoral race after losing her re-election bid in the Republican Senate primary against Delegate Johnny Mautz, falling 75 percent to 25 percent.

"Thank you, Cambridge," Rideout posted on his campaign website after the results were announced.

"Thank you for your support, your contributions, your help, your vote, and what you will do to help our city be an even better place to live,” he wrote. “Thank you also for those who did not vote for me, I want and need to hear from you and to have your support for what our City Council, city manager, and police chief want to do to improve our community."
