Opponents of same-sex marriage in Iowa say they plan to push hard in the 2010 legislative session for a vote on a constitutional amendment that would limit marriage to one man and one woman.

Fox News reports that the Iowa Family Council is angling to have activists blanket the capitol on January 12 when Gov. Chet Culver delivers his Condition of the State address to a joint session of the general assembly with Iowa supreme court justices present.

This is the first time all three branches of the government are expected to be together since the Iowa supreme court's unanimous April 3 ruling that cleared the way for same-sex unions in the state.

Unlike in California, a constitutional amendment needs the approval of the general assembly in Iowa before being put on the ballot.
