The lesson IMO is to rebuild the whole political system, on a foundation made of sane rules. (And that should obviously include all government agencies, especially those which have been corrupting democracy for a few decades now.)
EDIT: Don't forget that one of the earlier whistle blowers said (a few months back) that Obama had been put under surveillance by the NSA as well [0], which means
a) you should expect him to have been vetted by the powers in place before being admitted as a presidential candidate by that 1 of the 2 parties available,
b) "they" have stuff on him and can handle him like a puppet that he seems to have become.
Ergo, it's not about which puppet you elect, it's about the system.
