Not that they all agree with it, but Congress authorized the government’s expansive surveillance powers and either knew about it or had neglected to know about it despite being offered the right to know about it. That’s the main reason that recent revelations haven’t been politicized like the IRS thing or Benghazi.
On the plus side, there are people on both sides of the aisle who think that surveillance has become too pervasive. That means, at least in theory, that there is some hope of adding transparency and safeguards to the system in an effort to better protect our privacy and prevent abuses. If Rand Paul runs for president, I am sure he will talk about surveillance issues. I expect it will be a topic on the Democratic side of the aisle, too.
