We'll see how much of the Republican Leadership in the House supports this.
On the one hand, it is trying *something* in Congress, OTOH, the question is whether things like this move the Overton window even if there is little chance of it passing. (I'm not sure which is easier, counting the 34 Senate Democrats who would *boast* of voting against it or the 13 states with SSM or Civil Unions and at least one house of the State Legislature with Democratic Control.
I'm not sure what the last Constitutional Amendment that passed with the leadership of one of the two political parties deadset against it. (16th /Income Tax?)
