Anything can happen. Especially when people cannot get behind a candidate that may not have all the same views and ideals as that person wants.
Not so many look at the big picture, and are too caught up in wanting everything NOW. Problem is when you want everthing NOW, you generally start losing more of what you got. Once lost, hard to get back.
Just VOTE and encourage other to do so as well. It's discouraging, I know, however, it is YOUR VOICE, if you don't speak it, you'll lose that too.
