Ohio Senator Sherrod Brown, a Democrat, on Monday helped launch an educational campaign aimed at increasing support for gay marriage in Ohio.

The Why Marriage Matters Ohio launch announcement was held in Cincinnati, Cleveland and Columbus simultaneously.

“All Americans should be able to marry the person they love, and they should be able to celebrate that love in Ohio,” Brown said in Cleveland. “Full rights should not vary by geographical lines. Why Marriage Matters Ohio will bring this issue of equal rights to the forefront.”

The campaign has the backing of the Equality Ohio Education Fund, Freedom to Marry, the Human Rights Campaign Foundation and the American Civil Liberties Union Foundation of Ohio.

The move comes three months after an effort to repeal Ohio's 2004 voter-approved constitutional amendment limiting marriage to heterosexual couples was pushed back from 2013 to at least 2014.

Speaking in Columbus, Elyzabeth Holford, executive director of Equality Ohio Education Fund, said that the Marriage Matters campaign is “part of our roadmap to fairness and dignity for all Ohioans.”

Several recent polls show Ohioans divided on the issue of marriage equality, though a March survey commissioned by The Columbus Dispatch found a majority (54%) of Ohioan back repeal of the marriage ban.

The debate in Ohio, at least in the short run, appears to be taking shape in the courts. A federal judge has ordered Ohio officials to recognize the out-of-state marriages of two gay couples.
