"Who voted against it?"
More than those that voted for it. With 67 needed for passage, this was not even in the neighborhood of winning passage. But, the campaign issue got it's day in the sun.
Every one said we would get only a third of the votes. Turns out we are 19 short. This means we have our work cut out for us. But this issue is NOT going to go away. The amendment will certainly be back if liberal activist judges keep trying to undermine marriage. Count on it.
