(CNN) - The ranks of Senate Democrats who back same-sex marriage grew Friday morning by two as Indiana's Joe Donnelly and North Dakota's Heidi Heitkamp came out publically in support of overturning a federal law banning marriages between same sex couples.
"With the recent Supreme Court arguments and accompanying public discussion of same-sex marriage, I have been thinking about my past positions and votes. In doing so, I have concluded that the right thing to do is to support marriage equality for all," Donnelly, elected last November, wrote in a statement on his Facebook page.
Heitkamp, who also won election in 2012, wrote that after "speaking with North Dakotans from every corner of our great state, and much personal reflection, I have concluded the federal government should no longer discriminate against people who want to make lifelong, loving commitments to each other or interfere in personal, private, and intimate relationships."
Both Indiana and North Dakota are conservative-leaning states.
With Donnelly and Heitkamp's announcements, there are now four Senate Democrats who have not backed marriage rights for gay and lesbian couples: Tim Johnson of South Dakota, Joe Manchin of West Virginia, Mark Pryor of Arkansas and Mary Landrieu of Louisiana.
Landrieu told CNN National Political Correspondent Jim Acosta in an interview Friday that she personally believes "people should love who they love and marry who they want to marry," but that her obligation rests with the people of Louisiana who elected her.
"My state has a very strong constitutional amendment not only against gay marriage but against gay partnerships. So I'm looking at the people of Louisiana trying to represent their interests," she said.
Two Republican senators have announced support for same-sex marriage: Rob Portman of Ohio and Mark Kirk of Illinois.
The Supreme Court heard oral arguments last week in two cases on the issue, including a challenge to the federal Defense of Marriage Act that defines marriage as between a man and a woman.
can't wait for same sex divorce, child support and custody law. wow this is going to be great?
Oh, so they were angels... so it wasn't men demanding to have sex with men.
So rape of Lot's daughters would have been OK? And he was saved from what happened to S&G... yet his wife was killed just for looking back. SMH?!
You miss the whole point of the story... trying to explain it to you would be an exercise in futility.
Can not wait to see the day when what? Humanity reverts back to the days of ancient Greece and Rome? Didn't fair well then either. Or you can't wait to see the day when children are taught and confused by idiot adults as to what gender they are? Or maybe when after SSM take place, you can't wait for the next legal challenge that will be for group marriages, etc.? Or perhaps you can't wait for a quasi minority group (created to advance an agenda) to dictate to the rest of the population what moral position they should take up?
