Montana Senator Max Baucus has reversed course on his opposition to gay marriage. Baucus, who in 1996 voted for passage of the Defense of Marriage Act (DOMA), has endorsed marriage equality.

DOMA is the law which forbids federal agencies from recognizing the legal marriages of gay and lesbian couples. The law also allows states to decide whether they want to recognize such unions.

The 70-year-old Baucus, who began his Senate career in 1978, announced his endorsement after Montana Democrats at their state convention last weekend endorsed gay nuptials.

Democrats unanimously voted to alter their party's platform to include the following passage: “We support repealing Section 7, Article 13 of the Montana Constitution. All adults should have the right to legally marry another adult of their choice, regardless of sex or gender. We believe same-sex spouses should have the same legal benefits, protections and responsibilities granted to all those who marry.”

Top Democrats were asked their stand on the issue at the convention, the Independent Record reported.

Baucus released the following statement: “I don't believe the federal government should be getting involved in people's private lives. Adults should be free to choose who they spend their lives with a committed relationship.”
