My personal opinion is that the real purpose of Obama is to distract from Benghazi, the IRS scandal of targeting conservative groups, unhappiness over Obamacare and so on. And he is certainly succeeding. I don’t think he cares what really happens regarding Syria — he will blame it on Congress either way it comes out and in the meantime nobody is talking about the other issues which ARE the real ones of concern to us, or should be, since they directly affect us.
It’s an out either way - if it is voted down he will blame Congress. if he goes forward with it and it is a disaster, he will say that it wasn’t just him, it was Congress as well. Same way he is now blaming “the world” for the red line.
