Reagan was well behind Carter right after the primaries and he won overwhelmingly
Not a good comparison.
Reagan was running against an very unpopular incumbent, Reagan shored up the conservative base, the demograhics were different, and Reagan did not have near 70% negative rating by the voters.
I cannot predict what will happen in Nov. But I can predict we will be saying Madam President if Trump doesn’t change how he has conducted himself during the primary campaign. My prediction is he won’t. But we’ll see
Clinton is very low on favorably, most see her as a liar. Trump has summed that up well by referring to her as crooked Hilary. She is not popular among millennials that is why Sanders is giving her strong competition for the nomination. So with the Dem candidate with no accomplishments and poor favorability the race is going to be very competitive. No democratic Presidential candidate has been elected 3 times in a row I believe since Roosevelt so history is not on their side. The economy is the main issue and Trump is uniquely positioned to turn it around. Clinton knows nothing about business and is hostile to free enterprise and cannot solve economic problems. Trump has an excellent opportunity to win the Presidency.
