I don't think the emails should be hacked. The government should pursue those who did it. Regardless, once the information is out, people should be able to use the information in voting. (And, by the way, it is only a matter of time before this same thing happens to the Republicans. That should be interesting. It is what it is.)
I don't trust HRC/Obama when they say it is the Russians. They could be telling the truth, but they have no credibility on this issue. That's what happens to liars...even when they tell the truth, people can't trust them.
If it is the Russians, we need to protect ourselves better. For example, we could require our Secretary of State to not have a personal server, or use unprotected phones in restricted areas. Basic stuff. National espionage will occur. We need to protect against it better.
