I wonder how many people actually care about this issue, as opposed to those who "care" only for the political benefits may or may not provide.
I'm guessing somewhere between 0 and 12.
I don't know how many people care, but I think people SHOULD care.
Should they care enough to not vote for Hillary? That's up to them. But she's lied and been secretive about matters of state in a way that is not in the public interest. She has conducted herself at the State Department in a way that, unquestionably, has the APPEARANCE of impropriety, and it's not been fully probed, in no small measure, because she has been obstructive.
Voting this year involves people doing the best they can choosing between the most imperfect options of my lifetime. People should not just ignore Trump's behavior, but they shouldn't just ignore Hillary's e-mails, because it involves action on the part of a candidate that was deceptive and illegal (even if not criminal) while in the public trust. There are folks who are upright and those who need to be kept upright. Hillary's in the latter category, and that's hardly what one should view as acceptable in a Presidential candidate.
