I have a suspicion, being a Senator for 40 years sort of removes you from the concerns of everyday Americans.
These are the same Senators (and Representatives) that vote for these measures. They'll never be the target of these surveillance schemes... and when they are, they throw a huge fit[1] because they're supposedly above all of it. They're the same people who ban guns from the public, but own operate and illegally traffic them themselves[2].
They're the same ones that don't have to be strip searched every time they fly, but I digress...
