"When the president does something -- that means it is not illegal." -- Richard M. Nixon
Nixon would be freaking out over what politicians get away with today and never have to resign. In fact their successors simply up-the-ante.
Remember how hated Bush's lawyers were? Now we know why Obama didn't prosecute any of them.
The next Nixon will bring a reign of terror down on the US (regardless of which party he comes from), using the laws that Clinton, Bush and Obama and others have passed.
