This year’s election night is likely to be an important one for the LGBT history books: Voters in Massachusetts are expected to elect the nation’s first-ever openly gay state attorney general, and voters in Maine could very well elect the nation’s first-ever openly gay governor. Two candidates for Congress could well become the first openly gay Republican elected to the U.S. House and, if they both succeed, they will join what will number as the largest ever contingent of openly LGBT members of Congress — up from seven to as many as 12, if all newcomers are successful.
