If election results hold up, incumbent Kelly Fergusson is out and newcomers Ray Mueller and Catherine Carlton are in as members of the Menlo Park City Council.
As of 11 p.m. with 17 of 21 precincts counted, Mueller led with 3,802 votes, or 26 percent of the ballots cast, followed by Carlton with 3,623 votes, 24.8 percent and Fergusson with 3,326 votes, 22.8 percent. Two other challengers, Carolyn Clarke and Dave Bragg, followed with 14.1 percent and 12.3 percent, respectively.
In a phone interview, Mueller said he was "cautiously optimistic" about winning.
One of the two seats on the five-member council will be vacated by Council Member Andy Cohen, who decided against seeking a third term.
Mueller, chairman of the city's Transportation Commission, secured a number of strong endorsements including those of all five members of the Board of Supervisors, as well as the backing of Menlo Park Mayor Kirsten Keith, Vice Mayor Peter Ohtaki and Council Member Rich Cline.
Carlton, vice chairwoman of the city Parks and Recreation Commission, also had strong endorsements and was the top fundraiser in the race, collecting $21,453 as of Oct. 20.
Mueller said he and Carlton shared a similar message of "economic renewal, while at the same time preserving the city's small-town character."
Both candidates also won the backing of the city's influential pension reform supporters, who successfully shepherded to passage a 2010 ballot measure
Housing Commissioner Carolyn Clarke, a small business owner who lives in Belle Haven, also found herself out of favor with the pension reformers because she signed a ballot rebuttal against Measure L in 2010.
Bragg, a Menlo Park Fire Protection District firefighter and former Marine, struggled early in his campaign when it was revealed that in 2010 he filed for personal bankruptcy.
