Iowa Senate Majority leader Mike Gronstal is on a tear this week. On Monday he rejected Republican efforts to bring a constitutional amendment banning gay marriage to the Senate floor. Read his remarks here (scroll to the bottom) or watch the video:

On Tuesday Gronstal in effect dared conservatives to push for a Constitutional Convention, which might consider adopting an amendment to ban gay marriage. From the Des Moines Register:

"I'm inclined to hope they succeed, if that's their strategy," said Senate Majority Leader Mike Gronstal, who has saluted Friday's Iowa Supreme Court ruling legalizing gay marriage. "There's a lot of good, progressive issues that we could pursue: a woman's right to choose, guaranteed health care for all Iowa citizens, workers' rights -- so if there are people that want to help us get to a constitutional convention, that's kind of my dream world."

If Iowa voters approve a ballot initiative next November on calling a Constitutional Convention, the Iowa legislature will draw up rules for selecting delegates to that body. If the convention approves proposed constitutional amendments, a special election will be scheduled, and voters will consider each amendment separately, not as a bloc.

Some Iowa Republicans don't sound eager to roll the dice on this procedure:

Sen. Ron Wieck, R-Sioux City, said he will likely vote against holding a convention. "We have bumps in the road but we're operating pretty well without going in and messing with the Constitution," Wieck said.

Senate Minority Leader Paul McKinley said he will continue to push for a second route toward a constitutional amendment on gay marriage: votes by the Iowa House and Iowa Senate in two consecutive general assemblies followed by a vote of the people.

But McKinley understands why some might have an interest in a constitutional convention.

"I think the reason there is some appeal at least on the surface is citizens feel very disenfranchised from their government," McKinley said. "Democracies are crazy things. Sometimes the people want to do things that maybe the elites don't agree with."

Although I'm confident that over time a large majority of Iowans will come to support marriage equality, I confess that I am a bit nervous about the issue coming to a statewide vote in 2010 or 2011. At the same time, like Gronstal, I can imagine lots of good amendments that might come out of a Constitutional Convention.
