The 49ers continue their losing streak off the field as well as on, with the self-proclaimed soccer moms who have been taking a hard line with the team over Levi’s Stadium retaining control of the City Council.

“It was quite an interesting election,” Mayor Lisa Gillmor said after returns showed that all three of her fellow stadium spending critics — Debi Davis, Teresa O’Neill and Kathy Watanabe — were re-elected by healthy margins.

The councilwomen have called for an audit on how much city money is being spent on police, fire and other services at the stadium.

They had been the target of what Gillmor and community activists called a “dark money” campaign by a San Francisco group seeking to install council members who would be more friendly toward the team. The 49ers did not comment on the accusations, and also declined to comment on the election results.

After an initial wave of good feelings, the 49ers kicked over a hornet’s nest last year when they sought to take over youth soccer fields adjacent to Levi’s Stadium for parking. The result was a series of packed City Council meetings with soccer kids in uniforms talking about what it would mean to lose their fields.

Interesting to note that in Tuesday’s election, Santa Clara voters also overwhelmingly approved a measure requiring that any sale or development of the soccer fields be approved by a two-thirds vote of the people.

All this comes as the 49ers are seeking to renegotiate their rent deal with the city.

Should make for an interesting season.
