More than half of Wyoming residents support marriage for same-sex couples, according to a University of Wyoming poll.

The poll found 53 percent of respondents supported marriage for same-sex couples, and 39 percent did not. It’s an sizable increase from a decade ago. In 2004, only 24 percent of Wyoming residents supported marriage for same-sex couples.

“This represents a notable shift in public opinion, said Jim King, a professor of political science at the University of Wyoming, in a statement. “Every two years, approval would increase by a few percentage points. The rise from 40 percent approval in 2012 to 53 percent approval this year is a significant jump.”

The poll found self-identified moderates and liberals were more likely to support marriage for same-sex couples than self-identified conservatives, and young people were more likely to support it regardless of ideology than senior citizens.
