My wife asked me a similar question just a few minutes ago as neither of has ever been polled in our 69 years. I theorized that a person may have to sign up somehow to be polled but I don't know that for certain. Anyway, I believe that polls cannot be taken at face value because, in the case of our state of Pennsylvania, if the majority of the persons polled live in one of our metropolitan areas, a democrat will always be the favorite for the residents of those areas typically are more dependent upon the government programs like welfare that republicans legislators do not go out of their way to support. Conversely, residents of the less highly-populated central parts of the state resent how much of their tax dollars go to people whom they feel don't work and contribute their fair share so they tend to lean toward the republican candidate.
I've never been all that much into politics and tend to consider most career politicians with a lesser amount of respect as many of them seem to be after a good income without having to work very hard to get it. Also, too many times, all those campaign promises never come to fruition. Accordingly, while he is not a perfect candidate, I like that Donald Trump is not a career politician and already has so much money that he doesn't need another $450,000 per year. I think he won't cave into party pressure and will at least try to do what he feels is best for all Americans.
Of course, I could be wrong. But I still have to wonder what it is about the Clintons that makes Americans respect and like them so much. Both have been proven to be dishonest liars and just basically sleazy folks. I just cannot respect either of them and I've gone almost eight years without a president I can respect in office so I'm quite ready for a real change.
I for one have had my mind made up for a long time and Hitlery ain't on my list. Plus we need to change out as many reps as possible. I will not watch another debate(if that's what they call a cluster F nowadays).
Trust nothing that comes from the media in the United States. I believe the polls are fixed I think they're hoping if they show a big enough Hillary lead trump voters will give in and not show up at the polls. Polls don't represent everyone for example they only pull people that actually have a home landline phone not cell phones . The vast majority of people that I know don't even have home phones anymore only cell phones . I would really love it if they publish where they took these polls at by geographic location .
