Trumps negatives are fixable. Her’s are not.
Trump’s negatives are from two causes, 1, people do not know him (as it was with Reagan in early 1980,) and 2, to be totally honest, his mouth.
Trump can simply demonstrate he is a reasoned man, not a hip shooter, and that will take care of most of the second problem. Time will resolve the first.
Hillary on the other hand, has the exact opposite problem. Our dislike for her IS from knowing her, and will only get worse as the campaign continues and more people see her in a competitive environment.
Remember the other Hillary problem. A certain percentage of the people LOVE her, and the rest hate her. She has no one who just “likes her somewhat,” and in politics, that is deadly.
Of course, if she is indicted, and steps out, the Biden/Warren team are in within 72 hours.
Or as Manafort said, Trumps negatives are about personality, which are fixable. Hillary’s negatives are about character, which are not.
