Personally, I think you have only gotten a part of what the administration is doing. They are using the argument that NSA is overstepping its bounds to curtail terrorist surveillance. At the same time they intend to use NSA to identify those who are real and potential political threats to their Washington power.
The Tea Parties will accelerate this process.
Thats what Clinton did with his most effective political opponents. Obama will do the same only worse, because the MSM will refuse to cover the fact that the audits are all of conservative "right wing extremists." People shold be preparing for this and organize the disclosure of it for all to see.
