I am watching the executive order thing too but I bet some of the Republicans fold an play ball this term.I do not expect another AWB as it will need to pass through the house and that won't happen with the current house.
What I expect is executive orders and directives out of the DOJ. I'm not sure how can be done there, but it will certainly be an angle that will be examined.
Then there is the UN treaty. From my understanding, it takes 2/3 of present senators to pass. It does not take 2/3 of all senators, only 2/3 of those that are present when the vote is taken. With some creative scheduling this can be easily accomplished. All one needs to do is see how Charlie Rangel passed the Hughes amendment to see how easily our legislative system can be overridden.
As for the UN thing. What happens if we sign it but the senate does not pass it? How does that play out with the rest of the world? What we think an what they think may not be the same an may cause effects to us without ever being passes.
