I'm a CO resident, and I was honestly astounded that the measure passed with such a wide margin. I don't think people read or understood the measure. CO generally has a big libertarian streak (we're one of the states Gary Johnson did best in). I'm guessing the measure won on the strength of the name alone and not the merits of the actual law.

Now the usual suspects lined up against it, and that's who NPR interviewed: the Christian right out of Colorado Springs. However, I saw more opposition to this in my middle class gentrified neighborhood than I saw support or opposition for any measure, except maybe the tax measure to support the cultural district. This neighborhood is anything but conservative and this is one of the rare cases where seeing signs on the neighbors' lawns made me look deeper and actually change my vote from the reflexive "yes" to a "no".

The good news out of this election is that Prop 107 passed, which makes it harder to get constitutional amendments on the ballot. One of the things I dislike about living here is how the state is used as a political laboratory for everybody's pet poli sci project.
