Gay marriage foe Frank Schubert refuses to believe Americans are increasingly supportive of gay nuptials.

Schubert has devoted much of the last four years running campaigns opposed to extending marriage rights to gay and lesbian couples.

He ran California's 2008 Proposition 8 campaign, which overruled a state Supreme Court ruling legalizing marriage for gay men and women. He repeated that success in Maine the following year and North Carolina in May.

Schubert is currently the chief strategist of four ballot fights in Maine, Maryland, Minnesota and Washington state.

In an interview with SiriusXM OutQ host Michelangelo Signorile, Schubert said he did not believe national polls which show a narrow majority of Americans support marriage rights for gay and lesbian couples.

“I am not a big believer in most of the national polling on this issue,” Schubert said. “And mainly it's because I believe the polling, whether intentional or not, tends to skew the outcome, because it asks, for example, should same-sex marriage be legal or illegal.”

“Whether the public has shifted I think is very much open for debate,” he added.

As examples, Schubert noted polls conducted or paid for by opponents.

He went on to suggest that young people, considered strong supporters of marriage equality, will change their position on the issue as they grow older.
