A landmark California law that legalized the teaching of gay history in California’s public school might still be reversed at the ballot, months after an earlier signature drive aimed at overturning it fell short. Opponents of the law are trying once again to collect enough signatures to place the issue before California voters, and they believe they have a much greater chance for success this time, mainly because they have more time to gather the necessary 500,000 valid signatures. “Based upon we’re very confident that we will be able to be successful,” a supporter of the initiative says.
