It wont matter. Hillary supporters know she is a lying criminal but they just dont care.
Now, if some of those e-mails contained “unflattering and colorful” comments about current media talking heads, it might make a difference.
Consider that she would have to hold a press conference at that point. Now, not having stood for that since the campaign began, she might be a tad bit out of practice.
If nothing else, it will be fun to watch.
Look for something big to happen around that date. Something that might take our attention off of petty emails.
Perhaps an attempt on some visible person’s life, or a terrorist act, or a stock market crash...
Just an excuse to not debate or talk to the press. The next few weeks should be fun.
