Presidential candidate Donald trump has some very controversial policies. He wants to ban all Muslims from entering America, I don't see how he will enforce it because people can lie about their faith. I can say I'm Jewish when I'm not or I can say I'm atheist and be a Muslim. I don't see what is wrong with Islamic people anyway, almost all people that call themselves Muslim are harmless law abiding people.
Why build a wall across Mexico and not Canada? Why is he writing off a whole country? Somehow I think he would be doing mexico a favour by building a wall because he will keep the American criminals inside the US and force the drugs gangs to leave the border towns alone. Mexicans don't take drugs like they do in the US so the gangs would loose money and the other countries nearby would pick up the drugs trade. And all the subsidised cheap GM corn would stay in the US and stop undercutting Mexican farmers. Perhaps Mexico will get rich without America.
