Let’s review again:
As Secretary of State Hillary Clinton recklessly, in violation of government rules and reasonable common sense, used an unsecured private server for email communications, which endangered national security by exposing sensitive classified information to our enemies. She failed to preserve all those emails as required but instead destroyed them, and to cap it off, repeatedly lied about this to the public. Now, she thinks she deserves a promotion?! (This doesn’t even factor in the debacle in Benghazi for which she was also investigated and proven a liar, and wherein her incompetence is at least in part responsible for the deaths of four brave Americans).
Well, that’s Hillary/Obama logic. American logic ought to say in response:
“Mrs. Hilton, you’re out of order. A person who fails in lesser duties to do that required of them, and exposes America to serious harm, and expresses no regret but rather refuses to be accountable for their actions, does not deserve a promotion to higher duties! You have escaped justice for the moment, using your powerful White House connections. But at the ballot box, God willing, the American people will execute their own justice and you will be sent home. And if there is any justice left in this world, the next President will re-open this case and correct this travesty of justice today, and you will indeed face the proper consequences for your actions.”

I don’t have a clear sense this will matter much, and I admit I’m only guessing. I believe most voters only care whether and when someone is indicted or convicted of actual crimes. Everything below the level of prosecutions and/or convictions is assumed to be partisan yadda yadda. Nixon’s supporters never wavered until he was forced to resign to avoid prosecution.
