Considering US has a crime rate 10x higher than most of europe, i dont quite see that theory working out, and a welfare is a very small amount of the budget around 5%, and we are still pretty fine, like i said you have leaders who blow it out of proportion for political gain
You realize that the election isn't till next fall? And that he doesn't even have the republican nomination yet. So few people vote in primaries its hilarious. Explain the way he is going to do this beyond just saying it as well? It is a long road and you assume that every American is behind the idea of banning all refugees. Lots of assumption in your post. Also, you are assuming he actually wants to win, which I stand by the idea that he does not. He wants the fame. He wants to sell hats. He wants to get paid for speaking gigs and he wants another TV show. If you look at Palin she got all that. He is shooting for the same. Trump has no interest in actually working and being President. He wants all the glory none of the actual work.
Trump will win the nomination because people can relate to him. His proposed policies make sense, even if they cost a little bit to start off, they are redirecting this country away from the dangerous path it has been on for the last 20+ years. Aside from Trump and Bernie, these politicians running are as fake as John Rivers face. All Bernie and Trump have to do to win is focus on the failures of both the democratic and republican parties combined for the last 20-30 years.
