Three weeks after the Legislature voted to put the gay marriage amendment on the ballot in 2012, things are beginning to pick up steam.

Most notably, the state's campaign finance board plans next Tuesday to revisit a 14-year-old advisory opinion which said corporations -- both businesses and non-profits -- do not have disclose their own donors when giving to ballot question committees.

Activists on both sides of the marriage debate say the board's decision could have a major impact on the next 17 months, considering the National Organization for Marriage and the Human Rights Campaign are expected to pour resources into Minnesota. Different disclosure rules, depending on what they are, may change the role those groups play in the campaigns.
