We're going to make a great country again. We're going to start winning again. We're going to win a lot, it's going to be a big difference, believe me. It's going to be a big difference.
Trump uses his whole introduction on explaining how terrible America is right now. I don't think this is the best way to get Americans' support. Most Americans are very proud of their country and will not hear it spoken ill of. But because he ends it saying that he will fix all of this and "make America great again", he will most likely get the votes of those who agree with him and want a more traditional/old fashioned America.
