A new field poll finds a majority of Californians now opposed to amending their constitution to deny gay couples the right to marry:

The new poll, released today, is the first independent statewide measure of public opinion on the proposed constitutional ban since gay men and lesbians began marrying legally in California on June 16. It was also the first time Field Research has polled voters on the official ballot description of Proposition 8. A narrow majority of 51 percent of 672 likely voters said they would vote against a ban, while 42 percent said they would vote for it.

The anti-gay vote can be under-represented in the polls - but it's very rare for a proposition to come from ten points behind to win. Only 7 percent said they were undecided.
