So does your senator MORE (D-Mo.) announced her support for same-sex marriage Sunday night, becoming one of the first Democratic senators from a traditionally Republican state to do so.
McCaskill's statement, posted to her Tumblr page, precedes oral arguments at the Supreme Court on Tuesday and Wednesday on a pair of cases examining states' and the federal government's ability to define marriage as between a man and a woman.
"I have come to the conclusion that our government should not limit the right to marry based on who you love," McCaskill wrote. "While churches should never be required to conduct marriages outside of their religious beliefs, neither should the government tell people who they have a right to marry."

In her post, McCaskill says she was influenced by friends and colleagues in committed, same-sex relationships.
"My views on this subject have changed over time, but as many of my gay and lesbian friends, colleagues and staff embrace long term committed relationships, I find myself unable to look them in the eye without honestly confronting this uncomfortable inequality," McCaskill wrote. "Supporting marriage equality for gay and lesbian couples is simply the right thing to do for our country, a country founded on the principals of liberty and equality."
"Good people disagree with me," McCaskill said. "On the other hand, my children have a hard time understanding why this is even controversial. I think history will agree with my children."
