"Amounts to violating a work policy that many other people are also guilty of violating" is surfing Neogaf on your work computer, or eating fries behind the counter of a fast food joint. When you're head of the State Department, and charged with classified information at a high level, it's a big deal, and goes beyond "she just violated policy". People have been charged for being irresponsible with classified info. Typically misdemeanor charges, when it's unintentional, but they've been charged.
In fact, Hillary Clinton would throw Edward Snowden in prison for mishandling classified information.
Politics are a team sport, but we should hold our representatives to a higher standard. When you are running for the head of the military apparatus, placing your own convenience and personal secrecy ahead of national security is NOT a great selling point.
Yeah, this argument for Trump is weird to me. I had some in-laws over yesterday and we had a pretty heated argument over Trump (my wife and I are voting Hillary but supported Bernie, they are both Trump voters). They had some charges against Hillary, that she was corrupt, that the Clintons have acted inappropriately, which were hard to refute, but their defense of Trump was hilarious. My wife's like- "he's said point-blank that he'll target the families of terrorists or suspected terrorists, which is unacceptable". They responded- "oh, he won't do that." But that's what he said he would do! It's not like we have anything except his statements to go off of. We know what kind of president Hillary would be, or we have a damn good idea. If you take Trump at face value he'd be an extremely dangerous president.
