Senator Tom Carper (D-DE) has come out for marriage equality in a post on Facebook:
As our society has changed and evolved, so too has the public's opinion on gay marriage – and so has mine. I pray every day for God to grant me the wisdom to do what is right. Through my prayers and conversations with my family and countless friends and Delawareans, I've been reminded of the power of one of my core values: the Golden Rule. It calls on us to treat others as we want to be treated. That means, to me, that all Americans ultimately should be free to marry the people they love and intend to share their lives with, regardless of their sexual orientation, and that's why today, after a great deal of soul searching, I'm endorsing marriage equality.
Carper joins a list of Democratic Senators who have come out for marriage equality in the last week. Only seven remain who haven't declared their support.
They are: Joe Donnelly (D-IN), Tim Johnson (D-SD), Heidi Heitkamp (D-ND), Mary Landrieu (D-LA), Joe Manchin (D-WV), Bill Nelson (D-FL), and Mark Pryor, (D-AR).
