Trump may or may not be a blantant narcissist, but he MIGHT have a good chance of winning the nomination and subsequent election. It is possible that a groundswell of angered Americans could put him over the top.
As for stirring up the pot -- the pot has already been stirred by the violent crimes committed by some of these aliens who are also criminals. Not all of the Mexican aliens are criminals -- probably most of them are not.
But there are still significant numbers who do commit crimes -- including murdering American citizens. Trump NEVER said that all Mexicans are criminals -- that would be idiotic to say such a thing and equally idiotic to believe he really said that.
He is representative of a huge number of Americans who are sick and tired of both parties talking about -- but never doing anything about -- our open borders. People from most countries -- including Mexico -- are welcome to come through the FRONT DOOR to our nation and do it the right, and legal, way.
In the meantime, it is the violation of any nation's sovereignty for people to sneak in across its borders. And no nation, including the USA, should tolerate it.
And, if Trump is the one man who would take real steps to seal up our borders -- and deport all criminal aliens -- he is the man who should be the next president.
Another man who I think would take action to protect our nation is Scott Walker. In reality, Walker is probably the most likely to win the Repub nomination.
