As I recall it the "Bush" admin got caught doing much worse (our foreign allies don't have constitutional rights, and keeping an eye on your friends is standard practice in the clandestine world, so whoopty shit)
Spying on Americans and other branches of government illegally (telling FISA courts to fuck off) is a bit more severe. He (well, Cheney) had the NSA spy on veterans, the State Dept, Colin Powell (that guy who was "out of the loop"), Justice Scalia, Justice Alito, journalists, and a number of high level military brass. This coming from "Mr. Unitary Executive" too.
I think it speaks to Obama's credit (albeit ever so slightly) that he took the time to at least set up a legal framework behind his programs, regardless of what I think of them. I just don't see Obama spying on Kerry, or treating Veterans like sleeper agents because they disagree and speak out on military strikes against Ghaddafi or Assad.
Obama still deserves all the shit that comes his way over the "data collection" issue, I don't really feel any amount legal justification can support doing that to law abiding American citizens within their own country. But to say he's going about using the NSA in the same (or more inept) manner just doesn't work.
Both admins have an absolutely despicable history with whistleblowers though, and that did surprise me with Obama.
