It looks like the state Supreme Court is on its way to upholding Proposition 8, thereby keeping gay marriage illegal. The key to today’s historic hearing was Justice Joyce Kennard, one of the four justices who voted last year to legalize same-sex marriage. It was clear from today’s hearing that Kennard intends to uphold Prop.8 and bow to the majority of voters who voted for it. That means gay marriage supporters have to hope that one of the justices who voted last year against gay marriage will switch his or her vote — an unlikely scenario. It looks like state-sanctioned discrimination will win the day.
