Californians are about evenly divided on a proposal that would require schools to allow transgender students to participate in sports and use bathrooms based on their gender identity and not their sex, according to a new USC Dornsife/Los Angeles Times poll. Forty-six percent of registered voters said they opposed the measure. Forty-three percent were in favor. The margin of error is 2.9 percentage points in either direction. The proposal was approved by the Assembly last month and is now headed to the state Senate. Assemblyman Tom Ammiano (D-San Francisco), the bill’s author, said it would help make transgender students feel comfortable in school and ensure that they could fully participate in activities.
