Without recourse to congress, it goes without saying.
Obama has run all over congress. If he can change the law, he’ll even run over the courts. In effect, he has now opened up a war on two fronts with his power grab. Congress and the courts will, if for no other reasons, fight him to protect their own authority. If they don’t they’ll become irrelevant and the country will be a dictatorship. I predict Obama will suffer a huge defeat on this issue.
