In an election in the city of Santa Clara CA midway through Early Voting, city voters appear ready to approve Measure J, to build a new stadium in Santa Clara for the NFL 49ers, according to a SurveyUSA poll conducted exclusively for KPIX-TV in San Francisco.

56% tell SurveyUSA they are certain to vote Yes on Measure J; 40% are certain to vote No. The measure is backed by a majority of men and women … young and old … whites, Hispanics and Asians … Democrats and Republicans.

Among the 37% of voters who tell SurveyUSA they have already voted, the measure passes 2:1. Opposition to ballot measures typically increases as Election Day approaches. In states with a month of Early Voting, it is unclear if the same electoral dynamics apply.
