Minnesota Secretary of State Mark Ritchie is changing the title of the constitutional amendment to “Changes to in-person & absentee voting & voter registration; provisional ballots." Sponsors of the measure, seeking to require voters to show a photo ID before casting a ballot, want the question titled "Photo Identification Required for Voting." Ritchie is being sued for changing the title on the marriage amendment question.

Secretary of State Mark Ritchie has submitted the title “Limiting the Status of Marriage to Opposite Sex Couples" to Attorney General Lori Swanson for final approval, the Associated Press reports. Supporters of the constitutional amendment want it titled, "Recognition of Marriage Solely Between One Man and One Woman."

The battle over the marriage amendment may be the most expensive fight ever in Minnesota over a ballot initiative, the Star Tribune reports. Even actor Brad Pitt has donated money. Opponents of the measure raised more than $10 million, and supporters raised about $5 million. Supporters of the other ballot measure, a constitutional amendment that would require voters to bring a photo ID to the polls, raised about $1.5 million, and opponents raked in $2.6 million.

Black voters in Minnesota are the latest audience sought by opponents and supporters of marriage amendment, the Star Tribune reports. The president of the national NAACP was in the state Monday to urge black voters to reject the ballot measure that would ban gay marriage. Church leaders are divided.

Supporters of the constitutional marriage amendment have filed a lawsuit asking the Minnesota Supreme Court to change the ballot title question back to “Recognition of marriage solely between one man and one woman." Last month, Secretary of State Mark Ritchie and Attorney General Lori Swanson changed the tittle voters will see in November to “Limiting the status of marriage to opposite sex couples.”

The pro-marriage amendment group Minnesota for Marriage Friday called into question Minnesota Secretary of State Mark Ritchie's actions after he unilaterally rewrote the title of the ballot question Thursday without warning. The group is requesting correspondence between Ritchie and state Attorney General Lori Swanson, who are both Democrats, and other documents. The group says the new phrasing hurts their cause.

With a healthy lead in the polls, Sen. Amy Klobuchar, D-Minn., is spending some of her political capital in the divisive fight over the marriage amendment. In a new email to potential donors, Klobuchar says she has pledged to help raise $10,000 for the fight against the controversial state ballot measure that would define marriage as between a man and woman.

Discussions about same-sex marriage have been playing out in faith communities for years, and the debate has grown louder in Minnesota as a vote looms on a constitutional amendment defining marriage as between a man and a woman. Catholics and evangelical churches strongly support it. On Thursday, more than 100 religious leaders who oppose it will hold a faith summit in Minneapolis.
