The gay daughter of New Jersey gubernatorial candidate Barbara Buono criticized Gov. Chris Christie on Monday for his opposition to same-sex marriage. Tessa Bitterman sent an email to her mother's supporters saying she has a stake in the election because she is a gay American. Buono, a Democrat, supports same-sex marriage. The governor, a Republican, does not. "As governor, he has been a giant roadblock to New Jersey achieving equality for all," she wrote. Christie vetoed a gay marriage bill last year. Democrats have since said they plan to try for an override, but haven't yet done so. They have never been successful at overriding a Christie veto, which would require some Republican support.
