This begs the question, how is hacking the DNC server a national security concern? The DNC isn’t a government entity and they couldn’t have national secrets to be exploited.
To me, the biggest national security concern in the whole matter is that John Podesta -- who previously served as a senior advisor in the Clinton administration on matters of electronic privacy and telecommunications security -- was dumb enough to fall for a phishing scam that is usually targeted at octogenarians who barely even know how to turn on a computer.
This certainly IS a national security issue. The American people are wising up to the fact that our country has been run by morons for years ... and we can't have that, now can we?
