This sentence structure reminds me of the global warming argument. If we don't do X, the temperature could increase by Y within the next Z years. "Could" and "may" are über vague terms that mean nothing. They're just conjecture terms that are used to put fear in people whose minds the speaker wants to change. These words have no power with me. I don't believe in man-man global warming, and I don't believe Trump is an acceptable candidate for president.
BTW, don't get me wrong. I don't mind that he's focusing on the problem. He just not the person to fix it. As I've said before, he will never get my vote.
