Obama Backs Same-Sex Marriage - A one-stop shop on Robin Roberts' exclusive Good Morning America  interview with President Obama  is a one-stop shop with all the video clips, a timeline and history  - http://abcn.ws/IDrLEt

"I have to tell you that over the course of several years as I have talked to friends and family and neighbors, when I think about members of my own staff who are in incredibly committed monogamous relationships, same-sex relationships, who are raising kids together; when I think about those soldiers or airmen or marines or sailors who are out there fighting on my behalf and yet feel constrained, even now that 'don't ask, don't tell' is gone, because they are not able to commit themselves in a marriage, at a certain point I've just concluded that for me personally it is important for me to go ahead and affirm that I think same sex couples should be able to get married," Obama told Roberts. The fullest report from the wide-ranging interview will be on ABC's "Good Morning America" Thursday. Excerpts also on World News and Nightline today.

Richard Soccarides to Devin Dwyer - "The struggle he's had on this issue and how and why he's ended up where he has… will be helpful to all Americans who are struggling with this," Socarides said.  "I think that the fact that he was thinking about this for awhile - neither yes, nor no - was where many Americans are." - http://abcn.ws/IDrLEu

Log Cabin Republicans Bristle at Manipulation - ""That the president has chosen today, when LGBT Americans are mourning the passage of Amendment One, to finally speak up for marriage equality is offensive and callous," said R. Clarke Cooper, Log Cabin Republicans executive director. "Log Cabin Republicans appreciate that President Obama has finally come in line with leaders like Vice President Dick Cheney on this issue, but LGBT Americans are right to be angry that this calculated announcement comes too late to be of any use to the people of North Carolina, or any of the other states that have addressed this issue on his watch." - http://abcn.ws/J1BnHJ

Ralph Reed Predicts Backlash - "This is an unanticipated gift to the Romney campaign.  It is certain to fuel a record turnout of voters of faith to the polls this November."

What Same Sex Marriage Polling Today Tells Us - From Gary Langer and the most recent ABC News / Washington Post Polls -

Men 50 percent support, 45 percent oppose.

Women 54 percent support, 41 percent oppose.

Independents 54 percent support, 42 percent oppose.

And the following from our last two polls combined -  Whites 54-43. Blacks 41-55. Hispanics 49-42.

Langer - "Polling has shown dramatic increases in support for gay rights over the years. Slightly more than half of Americans support gay marriage, 52 percent in our most recent ABC/Post polling on the subject (in March). That's risen sharply in recent years, reached a majority about a year ago and has remained there since. There are striking differences by age, partisanship and ideology."

But will it Matter? Out at the Royal Cuts Barber Shop in Manassas, Virginia, Charles Robinson, Owner and Sole Proprietor, recited some bible verse to ABC's Jack Date and explained his opposition to same sex marriage. But he said he wouldn't be taking the Obama 2012 sign out of his window.

Consider this - Romney was Governor when Massachusetts became the first state with legal same sex marriage. Add that to the oddity of the man who first enacted a universal health reform law running against the guy who did it for the rest of the country.

But Romney's Marriage Position Isn't Evolving - He's still opposed to it - "I have the same view on marriage that I had when I was governor and that I have expressed many times: I believe marriage is a relationship between a man and a woman," said Romney at an impromptu news conference following a speech in Oklahoma City this afternoon. "States are able to make decisions with regards to domestic-partnership benefits, such as hospital visitation rights; benefits and so forth of various kinds can be determined state by state," said Romney. "But my view is that marriage itself is a relationship between a man and a woman, and that's my own preference. "I know that other people have differing views," he added. "This is a very tender and sensitive topic, as are many social issues." - More from Emily Friedman - http://abcn.ws/JubhRI

Boehner Says on Fox Business Network This is a Distraction - "I think he made his position pretty clear. I have always believed that marriage was between a man and a woman. But Republicans here on Capitol Hill are focused in on the economy. The American people are still asking the question where are the jobs? And our focus is going to continue to be on the economy like it has been for the last year and a half. "
