From Foreign Policy:

The American people believe that the National Security Agency may have gone too far in spying on U.S. allies. They also think that the NSA has intruded on Americans’ personal privacy in scooping up massive amounts of private phone calls and emails. But don’t expect to see citizens taking to the streets. In fact, in the pursuit of terrorists, a majority will still trade privacy for security. And while it’s pretty clear the NSA is watching, it’s unclear to what extent Americans care.
