Phil Burress, president of Citizens for Community Values, says “you can't allow same-sex marriage until you destroy all religions.”

Burress and his organization led the campaign to approve Ohio's 2004 constitutional amendment which prevents the state from recognizing any relationship other than a heterosexual marriage.

Backers of an effort to repeal the amendment say Ohio Senator Rob Portman's recent endorsement of marriage equality has re-energized their campaign.

“The senator's coming-out in support of freedom to marry has absolutely re-energized the campaign,” Ian James, co-founder of FreedomOhio, told the Cleveland Plain Dealer. “This is a monumentally huge step in Ohio, a battleground state, for the marriage equality movement.”

Burress disagreed, telling the paper that “I just don't ever see it happening.”

“This nation was founded on Judeo-Christian principles, and, like Judeo-Christian beliefs, every major religion is opposed to same-sex marriage,” he said. “You can't allow same-sex marriage until you destroy all religions.”

Burress also chided Portman for putting the Republican Party “at risk.”

“He has definitely put himself in the crosshairs for the next election,” he said. “You can't win an election in Ohio without the evangelical vote.”
