In looney left land such theories might sound great but in the real world it will force democrats in congress to either support him and vote for an unpopular action or turn him down and make it look like his military actions are not even supported by his own party. Go ask David Cameron how that works. In the end he will either have to act against the will of congress or setback and accept their authority. This has lose written allover it for Obama.
Now of course his most rock solid fan base, the media, will carry water for him and that will help but they are not much more popular or trusted than congress these days.
