I was referring to the "build the wall" reference in the comment I replied to. And yes, he tends to run his mouth without fact-checking which is one of the reasons I don't like him.

That said though - the core issue he is exploiting is an undeniable failure of the federal government to address the illegal immigration problem. It's a huge issue that has been swept under the rug and is there to be exploited by a politician like Trump who positions himself as a "non mainstream politician".

Violent[ish] protests staged by the left waving mexican flags and burning american flags only helps his agenda.
