I watched some of Bubba’s speech. I don’t see how it was helpful to Hillary at all. He began by telling a story with a timeline beginning in 1971. That’s 10-15 years before the demographic they need to sway to win was even born. As he spoke of watching her from afar, it was very easy to view him as a sexual predator, which we now know him to be. The more the story drug on, the more it just made Hillary appear to be an old, tired has been.
Rachel Madcow characterized the beginning of his speech as “rude and shocking.” I don’t pretend to be able to tell what she thinks, but she seemed to be offended because it made Hillary appear to be the lesser of the couple. Bill’s boy toy if you will.
Considering that “demographic” mentioned in your post now has become Bernie supporters or supports for Donald J. Trump. Hillary is not only is “yesterday’s news” but is so disliked.
