1. Trump has constantly stated how he believes the US has spent money and lives doing things for the rest of the world. He just did it with Canada this week saying "Canada exists because of the US'.

3. Republican voters have been told to not trust the experts, news, or the opposing political party which eliminates all outside sources of information. This allows them to make claims about our debt or why we shouldn't pay it and many of these voters won't get opposing views.
