WASHINGTON -- Dick Cheney says he didn't see the point of raising the issue of gay marriage in the 2000 presidential campaign, even though he supported it.

The former vice president suggested it wouldn't have done much good and probably would have sunk President George W. Bush's prospects for office. "Why?" he responded to ABC News when asked in a televised interview whether he should have pushed harder for gay couples to marry.

Cheney's daughter, Mary, married her longtime partner this June.

Cheney said of the wedding: "I'm sure it was fine. We wished them well. She wanted to avoid having it be a media circus or having it become part of the political debate. So Lynn and I were very proud and happy and congratulated them."

    The state initially began conducting gay marriages on June 16, 2008. On November 5, 2008, however, California voters passed Proposition 8, which amended the state's constitution to declare marriage as only between a man and a woman. In 2013, the Supreme Court ruled against that law, and the state shortly thereafter began sanctioning same-sex nuptials.
