I mean, look, me and my friends called 2,000 people in each of thr 50 states, and we got the same result. The economy was the biggest concern, terrorism was second. Trump was viewed as having a good temperament by only 39% of the respondents, but still, 55% said they would vote for Trump, 30% said they would vote for Hillary, the rest were split undecided, Green, Libertarian. That's 100,000 people called, straight out the phone books. Party affiliation split was (natrually) the same as generally reported by other polls.
Credible?
Wow so your results were 55/30 Trump over Hillary.
I have faith and hope that Americans are not so dumb as to vote for a known criminal enterprise—the clintooons.
I had to develop a poll as part of a graduate statistics course a long time ago. Putting together a representative sample is key to getting an accurate poll.
