The Ohio Democratic Party on Thursday officially endorsed an effort to repeal Ohio's gay marriage ban.

Ohio's 2004 voter-approved constitutional amendment prevents the state from recognizing any union other than a heterosexual marriage.

In an email to supporters, the party asked, “Isn't it time that we make Ohio the 12th state to embrace equality?” a reference to the recent passage of a marriage bill in Delaware.

The organization also unveiled a fundraising campaign revolving around the issue.

The group FreedomOhio began its effort to repeal the amendment last year. The Ohio Freedom to Marry and Religious Freedom Amendment would replace language in the Ohio Constitution excluding gay couples from marriage with inclusive language, thereby legalizing marriage equality in the state.

Ian James, a co-founder of FreedomOhio, has previously said that while his group will easily surpass the roughly 385,000 valid signatures needed by July 3 to qualify for this November's ballot, a decision to put the question before voters this year hinges on public support and available resources.
