Trump is slowly gaining momentum, but expect a lot of dirty tricks to appear out of nowhere.

Hillary is basically stonewalling it. I don't believe there are deep underlying causes to her voice failure, but she is carefully avoiding getting it uncovered in the popular media. This is why she is avoiding press conferences---too spontaneous---and getting behind schedule in her speeches. She needs to prep her voice---because it is seriously failing. This would be a PR disaster, regardless of what her mind is actually doing. At a press conference she would be put on the defensive, and her voice cracking and having coughing fits would look horrible.

So she avoids it at all costs. and issues carefully worded smokescreens. The debates could be the place where she really gets fried---but Trump may be too much of a gentleman to push it. Politics is a dirtbag, manipulative, conniving sport. Hillary could get smeared all over the stage under the right kind of pressure.
