Every politician has their own set of corporate paymasters, and they answer to them. When any of them -- even the president -- dares to disobey, retaliation is swift (as evidenced in another story here on Techdirt). Obama will sign SOPA if it winds up on his desk, because he knows he can't be elected without all that Hollywood lucre pouring into his campaign coffers. And since the mainstream media (also the property of the corporate oligarchy) consistently succeeds in convincing Americans that they only have two choices when it comes to any political office, you will never see any third party candidate pose a genuine threat to the status quo.
Take your pick: high taxes, corporate welfare and the destruction of the free Internet, or compulsory Puritanical values, corporate welfare and the destruction of the environment. Those are your choices across the board come November.
