This makes little sense. Would you prefer if Huckabee offered a "broad" amendment that said that biblical law takes precedence or was written with broad strokes which a future activists court might interpret that way?
Using the abortion issue as an example, I would perfer he propose an amendement that said people's personal freedoms are allowed to be limited by the government when the legislature belived that it it better for the state for its own reasoning on an issue is better than that of the people. If he did that the amendment would have an even less shot at passing and the person who proposed it would have no political future. Instead, they merely choose an emotional issue and try to shove it down people's throat!
