The immigration laws are a classic example. Failing to get Congress to pass some version of amnesty, Obama 2 simply issued an Executive Order exempting certain classes of illegal immigrants from the immigration laws on the books.
Too many people have gotten sucked into a discussion of whether it is a good or a bad thing for people brought into the country as children to be exempted. But the whole reason for Constitutional government is to have all three branches of government agree on what the laws of the land shall be.
Obama 2 has decided instead that if Congress doesn't do what he wants, he will do it by himself through Executive Orders.
If any President can unilaterally change the law, we are not likely to have the same freedom under rule by presidential fiat as under Constitutional government. This is especially dangerous in a President's second term, when he need no longer have to consider what the voters want. With a couple more Supreme Court appointments he can permanently change the very nature of American government.
One of the most dangerous examples of a lack of transparency was inadvertently revealed last March when Obama 2, unaware that a microphone was on, told Russian President Dmitry Medvedev that, after he is reelected, and never has to face the voters again, he will have the "flexibility" to make a deal with Russia on missile defense systems.
In other words, Obama will be able to make a deal with a country that has been America's most implacable and most formidable adversary for more than half a century -- a deal he couldn't make if the voters knew about it before the election. Think about that chilling prospect, and what it reveals about the real Obama.
