If only it were true. In all polls, except the USA Today poll, he loses to either Clinton or Sanders. In the case of Sanders, he gets beaten by much more than the margin of error of the polls.
Do the math. Low Dem turnout like 12,000 in NV and high GOP turn out with Trump getting about 33,000 votes there. So how does the math work for him to lose. The media wouldn’t lie or feed you BS would they?
