"No free man shall ever be debarred the use of arms." - Thomas Jefferson, Virginia Constitution, Draft 1, 1776
So here is the problem as I see it. My wife actually told me about the story. Now she is highly educated (MBA) from UC Berkeley and represents (at least to me) the upper level education wise of the "uninformed voting mass." When she finished telling me about it, I asked her does it really matter to her or her friends? She said "no".
And there you have it, just like Benghazi, the Bosnian Sniper incident, and a whole host of other blemishes, the only people who really care are the ones that wouldn't have voted for Hillary in the first place.
