Of the 138 members of the Kentucky General Assembly, 107 have signed a brief in support of Kentucky’s ban on same-sex marriage, which is part of a case before the U.S. Supreme Court today.
The amici curiae, or “friends of the court,” brief is signed by 76 of 100 members of the Democrat-led House and 31 out of 38 members of the Republican-led Senate.
The legislators argue that states have the right to define marriage as being between one man and one woman and that heterosexual married couples are optimal for raising children.
“Raising of children by same-sex couples, who by definition cannot be the two sole biological parents of a child and cannot provide children with a parental authority figure of each gender, presents an alternative structure for child rearing that has not yet proved itself beyond reasonable scientific dispute,” the lawmakers argue in the brief.
The brief is signed by 37 out of 65 Democrats in the legislature—a reminder that Kentucky Democrats often skew socially conservative, even in the Statehouse.
University of Kentucky political science professor Donald Gross said the brief could help Democrats who fear the political perception of being “anti-family values.”
“If you’re a pro-choice, pro-gay rights Democrat, that can be a very significant issue in the general election,” Gross said.
