That's the whole point of these exercises. Obama knows full well that he will not be able to pass either a vast gun control scheme or an immigration program that lacks significant border enforcement. He has no intention of passing such legislation. He merely wants to propose such legislation to demonize his opposition as evil -- racist, uncaring about children and the like.
That's despicable. But for President Obama, such tactics are necessary in pursuit of his grand remaking of the American vision. The Constitutional vision believes in checks and balances; it assumes that men are neither angels nor devils but self-interested parties. But such a vision leads to gridlock, as the Founders well knew. Obama wants action. He is a man of action. And so his vision of man is different. There are good people -- people who agree with him --and there are bad people. With that moral dichotomy in place, the Constitutional system becomes obsolete and America awaits transformation.
