Go google - you’ll find several sites set up by Hillary supporters for McCain - Palin. Why waste their time if it’s fake? Many, many people go there daily and post.
Well, of course there are disgruntled Hillary supporters, but lots of people with time on their hands set up websites. I hope they represent "up to 10 million" votes, but a few hundred people making comments on a website doesn't mean a lot.
All that said, I hope there is some magic coming. The PUMAS have certainly helped me renew my faith that there are some of the D side who are patriotic.
