He can sign all the treaties he wants, still needs 67 Senate votes
I need to expand an earlier post. Obama has already bypassed the senate on a treaty they refused to ratify with an executive order and the senate, without enough testosterone to raise a slight woodie, did nothing to stop it. On the LOST treaty he will simply issue another EO and the Senate will cut our throats doing nothing to stop him.
The stuff that Obama is doing is irritating but it has no weight of law. He will be gone after Nov unless he is stupid enough to declare martial law and attempt to subjegate this huge country. If that happens he will be gone a lot sooner.
