Nowhere Is The Gay Marriage Shift More Clear Than In Ohio

In 2004, Ohio was one of 13 states to pass a constitutional amendment banning gay marriage. In 2013, the state seems ready to endorse the opposite position, according to a new poll commissioned by The Columbus Dispatch.

The new poll found that 54 percent of respondents now support overturning the ban and passing a measure that would "allow two consenting adults to marry, regardless of their gender." Just 40 percent oppose the proposal. And an astounding three-quarters of respondents under 25 support gay marriage.

That serves as a huge shift from 2004, when 62 percent of Ohio residents voted in favor of the constitutional amendment to ban gay marriage. As a key swing state in the 2004 presidential election, Ohio's gay marriage fight garnered most of the attention out of the 13 states that eventually banned it.

The poll comes at the start of the week in which gay marriage is primed to take center stage at the Supreme Court. The high court is set to hear two major cases involving gay marriage, taking up both Proposition 8, which banned gay marriage in California, and the federal Defense of Marriage Act.

Here's a chart showing the shift:
