Hillary’s support is lukewarm. Trump’s supporters are highly motivated. The polls are missing the turnout factor.
No one on the left is excited about Hillary. She is old, lumpy, shrill and dishonest. Democrat turnout will be light.
Trump represents change and the common man. After decades of the establishment rule, people are ready for something new.
Trumps speeches recently have been much more disciplined recently. He is asking for the black vote and is making the case that he can help them. He is asking for the votes of the blue collar working class and is pointing out the Democrats have abandoned them.
Trump will win on voters turning out for change away from the establishment.
The primary vote totals support your assumption. Republicans 30 Million WAY UP, Democrats WAY DOWN. This is a very good reflection of how the general election turns out. Trump will win, the week of the election suddenly many of the polls will show Trump ahead. Wait and see.
