Ensign's affair has a certain ironic twist. The senator, after all, billed himself as a "defenders of marriage." The Christian Coalition gave him a 100% score for his "pro-family voting record." He supported efforts to amend the Constitution to define marriage as between a man and a woman:
“Sadly, the effort to redefine marriage against the wishes of a majority of the people is, with help from activist judges, succeeding,” Ensign said. “In order to defend the institution of marriage, uphold the rights of individual states, and maintain the will of the people, I believe we are compelled to amend our country’s constitution.”
What Ensign doesn't understand is that equal protection under the law is guaranteed by the Fourteenth Amendment of the Constitution. If the majority deprives the minority of equal protection, such deprivation is indeed unconstitutional. His "defense" of marriage as exclusively heterosexual, along with his other arguments, is merely a smokescreen for the continued deprivation of equal marriage rights for gays.
Ensign is among other Republicans who have espoused "pro-family" positions, such as Newt Gingrich, who discussed divorce with his former wife Jackie as she recovered from cancer surgery; Mark Foley, who sent sexually explicit messages to teenage Capitol Hill pages; Larry Craig, who pleaded guilty to a misdemeanor after soliciting sex in an airport men's room, and David Vitter, who was linked to a prostitution ring.
Ensign and these other "defenders of marriage" have the right to matrimony while a loyal gay couple does not. That's perverted.
