Four years ago, Republicans rushed to pass a state constitutional amendment restricting marriage to one man and one woman within weeks of regaining control of the Iowa House. Every member of the GOP caucus was on the same page.

Two years ago, the marriage amendment failed to come up for a vote in the Iowa House, but a majority of Republican lawmakers still co-sponsored the legislation.

Now, signs point to Iowa House Judiciary Committee Chair Chip Baltimore letting the marriage amendment die quietly, as he did in 2013. Fewer than a quarter of the 57 House Republicans signed on to the latest effort to turn back the clock on marriage rights. At the same time, only one GOP lawmaker is “loud and proud” about supporting the right of all Iowans to marry the person they love.

Follow me after the jump for a breakdown of where Iowa House Republicans stand on the “traditional marriage” amendment, and speculation on why so many of them aren’t trying to pass it anymore, even though they ostensibly don’t support LGBT marriage rights.
