When Edward Snowden exposed the NSA's spying, most on the left and some on the right called him a traitor. True, he did expose some foreign spying operations (which should not be a surprise: nations spy on each other all the time: even friendly ones), but he also exposed a major constitutional violation. He has shown that trading liberty for security results in neither.
The news that Hillary Clinton maintained a private email server has been known for a year, but few have really thought about the damage this has done. It certainly proved that the attack on the Benghazi consulate in 2011 was not motivated by a YouTube video. Now news has come out that her emails contain a treasure trove of classified information (seriously pundits? media? this is a surprise to you?), but no one is calling Hillary Clinton a traitor, despite the fact that she is known to be a greedy and power hungry bitch, and has done nothing redeemable.
