Stanislaus County's nine mayors will be in Riverbank tonight to kick off their campaign to support Proposition 22, a statewide initiative that would prevent the state from taking money allocated for local agencies, public safety and transportation. Riverbank Mayor Virginia Madueño is holding the fund-raiser at her home. The event is from 6:30 to 8:30 p.m. and open to the public. The cost is $25 per person. There will be wine, and each mayor is bringing an appetizer that represents his or her city. The money raised from the fund-raiser will be used to promote Proposition 22 through such venues as radio and TV ads and pamphlets, Madueño said. She said the mayors also will work on their own to drum up support for the proposition. People wishing to attend are asked to call Madueño at 968-7052.
