During an appearance on NBC’s Meet The Press Sunday morning, Sen. Jeff Flake (R-AZ) admitted that a Republican presidential candidate who supports marriage equality is “inevitable” and that such a candidate would receive widespread support from across the political spectrum.

While Flake’s statement is reflective of rapidly shifting U.S. attitudes towards support for LGBT Americans — and come at the end of watershed week when the Supreme Court took up cases regarding the constitutionality of anti-gay laws Proposition 8 and the Defense of Marriage Act — it appears that cultural tide hasn’t quite swept up Flake with it yet, as the senator stood by his narrow interpretation of “traditional marriage” between one man and one woman:

CHUCK TODD (HOST): Let me ask you on gay marriage. Could you support a Republican presidential candidate some day who supported same-sex marriage?

FLAKE: Oh, I think that’s inevitable. There will be one and he will receive bipartisan support — or she will. So I think that yes, the answer is yes.

TODD: And where are you on this issue, you say it’s inevitable. Are you — Lisa Murkowski, a Republican colleague of yours called it evolving on the issue. Are you evolving to use her words on this issue?

FLAKE: I believe that marriage should be between a man and a woman I still hold to the traditional definition of marriage.

TODD: Is there something that you — are you thinking about it? Can you imagine changing your position before you left the U.S. Senate?

FLAKE: I can’t. I tell you, in the past I’ve supported repealing Don’t Ask, Don’t Tell. I’ve supported the [The Employment] Nondiscrimination Act as well, but I hold to the traditional definition of marriage.

Flake and other politicians opposing marriage equality find themselves on the wrong side of history and, increasingly, the opinion of the American public. Support for marriage equality has skyrocketed in recent years, and the latest election cycle saw the election of the first openly-gay U.S. senator, as well as the first openly bisexual U.S. congresswoman.

Still, a Republican nominee who supports marriage equality would face significant hurdles from members of their own party, as social conservatives have threatened to revolt if the GOP abandons its hardline views on LGBT rights and marriage equality. In fact, during a separate appearance on Fox News Sunday, former RNC chair Ed Gillespie hinted that the growing support for marriage equality could force Republicans to drop their call for a federal amendment against marriage equality from their platform.

Cardinal Timothy Dolan told ABC’s This Week on Sunday that gay people are entitled to “friendship” but not a long-last romantic relationship in the eyes of the Catholic Church.

Appearing on the program following oral arguments at the Supreme Court challenging the constitutionality of two laws targeting gay and lesbian couples, Dolan said that the Church should treat same-sex couples with love, while reminding them that “sexual love…is intended only for a man and a woman”:

GEORGE STEPHANOPOULOS (HOST): And you know, especially this week – because it’s been at the top of the news – for many gay and lesbian Americans –– gay and lesbian Catholics, they feel unwelcome –– in the Church. And what do you say as a minister, as a pastor – to a gay couple that comes to you and say, “We love God. We love the Church. But we also love each other, and we –– want to raise a family in faith. What do you say to them?

DOLAN: Well, the first thing I’d say to them is, “I love you, too. And God loves you. And you are made in God’s image and likeness. And – and we – we want your happiness. But – and you’re entitled to friendship.” But we also know that God has told us that the way to happiness, that – especially when it comes to sexual love – that is intended only for a man and woman in marriage, where children can come about naturally. We gotta be – we gotta do better to see that our defense of marriage is not reduced to an attack on gay people. And I admit, we haven’t been too good at that.

Dolan has been vocal in his opposition to marriage equality, repeatedly condemning the rights of same-sex couples under the guise of love and support for the gay community.

After lobbying against New York’s marriage equality law, Dolan prohibited by decree any Church personnel or property from being utilized for same-sex marriage ceremonies under penalty of “canonical sanctions,” calling the state’s law “irreconcilable with the nature and the definition of marriage as established by Divine law.” He has also compared the “threat” posed to marriage by gays and lesbians to that of polygamy, adultery, forced marriage, communist dictatorships, and incest.

Despite his rhetoric, a majority of New York Catholics supported the marriage equality bill months before it came to a vote and still do.
