| 2000 | R | R | R | We support the traditional definition of “marriage” as the legal union of one man and one woman, and we believe that federal judges and bureaucrats should not force states to recognize other living arrangements as marriages. . . we do not believe sexual preference should be given special legal protection or standing in law. | Vermont legalizes same- sex marriage | |
| 2003 | R | R | R | Mass rules that laws banning gay marriage unconstitutional |
||
| 2004 | R | R | R | We repudiate President Bush’s divisive effort to politicize the Constitution by pursuing a “Federal Marriage Amendment.” Our goal is to bring Americans together, not drive them apart. | We strongly support President Bush’s call for a Constitutional amendment that fully protects marriage, and we believe that neither federal nor state judges nor bureaucrats should force states to recognize other living arrangements as equivalent to marriage. We believe, and the social science confirms, that the well-being of children is best accomplished in the environment of the home, nurtured by their mother and father anchored by the bonds of marriage. . . Attempts to redefine marriage in a single state or city could have serious consequences throughout the country, and anything less than a Constitutional amendment, passed by the Congress and ratified by the states, is vulnerable to being overturned by activist judges. On a matter of such importance, the voice of the people must be heard. | Mass legalizes same sex marriage |
| 2008 | R | D | D | We support the repeal of “Don’t Ask Don’t Tell” and the implementation of policies to allow qualified men and women to serve openly regardless of sexual orientation . . . We oppose the Defense of Marriage Act and all attempts to use this issue to divide us. | Because our children’s future is best preserved within the traditional understanding of marriage, we call for a constitutional amendment that fully protects marriage as a union of a man and a woman, so that judges cannot make other arrangements equivalent to it. In the absence of a national amendment, we support the right of the people of the various states to affirm traditional marriage through state initiatives. | |

| 2012 | D | R | D | We support marriage equality and support the movement to secure equal treatment under law for same-sex couples. . . We support the full repeal of the so-called Defense of Marriage Act and the passage of the Respect for Marriage Act. | That is why Congressional Republicans took the lead in enacting the Defense of Marriage Act, affirming the right of States and the federal government not to recognize same-sex relationships licensed in other jurisdictions. . . We reaffirm our support for a Constitutional amendment defining marriage as the union of one man and one woman. | |

| 2016 | D | R | R | Democrats applaud last year’s decision by the Supreme Court that recognized that LGBT people—like other Americans—have the right to marry the person they love. But there is still much work to be done. . . Democrats welcome and honor all Americans who want to serve and will continue to fight for their equal rights and recognition. We are proud of the repeal of Don’t Ask, Don’t Tell and we commit ourselves to insuring fair treatment for LGBT veterans, including by proactively reviewing and upgrading discharge records for veterans who were discharged because of their sexual orientation. | ||
