How can you defend and preserve it if you think it is fundamentally flawed?
Today the talk shows are all talking about his redistribution of wealth views. They miss something more basic. Obama thinks the Constitution is flawed because it is all "negative rights." It wastes too much time on nots. "The states shall not ..." "The Government shall make no ..." Silly trivial stuff like that that get in the way of the Government's real purpose. This takes too much away from what Mr. Obama believes the Government's real purpose is -- taking from those who receive too much benefit from their efforts and giving it to those who only do the minimum necessary.
The Freedoms guaranteed by the Constitution should have been Roosevelt's "Freedom from Want". "Freedom of Speech". Freedom of Religion." and "Freedom from Fear". Well, at least the first one. The other three? Well, Freedom of speech interferes with our plan. Only superstitious bigots still cling to their bibles (and guns). And freedom from fear? You have nothing to fear as long as you do what we tell you.
No, Mr. Obama you are supposed to swear to preserve, protect, and defend this Constitution, not the one you wish it was, Even if you don't understand why the founding fathers designed it this way.
