1. The Clinton emails show a Secretary of State interacting with other people in the way of people who run large organizations do. There's nothing surprising there. It's exactly what you would expect. 

2. Clinton ran her own email server, as did the two previous Secretaries of States, both Republicans, neither of whom were investigated by Congress.

3. Whether or not you blame her for the deaths of four diplomats in Benghazi, Colin Powell, the Republican Secretary of State in 2003, is responsible for hundreds of thousands of deaths when he told the United Nations and the American people that Iraq had WMDs, thereby forming the basis for the war in Iraq. At the outset, not only did Clinton believe him, I did too. Most of us did, with reservations. When a high-ranking officer of your country says a war-starting country like Iraq has nuclear weapons, what choice do you have but to believe him? (BTW, this is one of the reasons we're so concerned about Trump as president, we would have no choice but to live with the consequences of him going to war as well.) Many hundreds of thousands of people died as result of Powell's lies. I hold him accountable even if the Republicans don't. 

4. I don't know if she destroyed emails, I've only ever heard Trump say that, not anyone else, and I don't think Trump ever tells the truth (or if he does it's the same way a broken clock is correct twice a day). But I remember when the Republicans were caught deleting 22 million very relevant emails, having to do with firings of US Attorneys covering up for some horrible crimes committed by Karl Rove, political director at the Bush White House. We knew about it, but it didn't make headlines. And the entire White House was using a private email server for emails they didn't want to be evidence in an investigation that clearly should have happened but didn't.

The "email scandal" was manufactured by Republicans to try to win the election. If she hadn't run for president I am sure there would be no FBI investigation. They have convinced Comey I guess that they can make him part of the scandal unless he bends over to do their bidding, which he has done. One party is willing to do any damage to the country to get their way. 

I would love to see Comey get up, after the election (for now he should STFU and let us try to have an election without the interference of the FBI) and admit he was wrong, and reaffirm that the FBI is non-partisan. After that we have to do something to reign in the Republicans, so they start acting in the interests of the country.
