I think Trump is an asshole with little understanding of the implications of his words. It seriously doesn't surprise me that much to see him getting widespread support, i mean, seriously, this is the country were George W. Bush got reelected.
Undocumented immigrants ain't much of a big deal, that's just the "america for americans" card. I would go as far as to say that the country where i live haves it much worse in that sense, were i live it's full of immigrants, and the hatred is not as nearly as overblown as it seems to be there. Sometimes it's baffling to see americans being so self absorbed. I understand it's an issue, but it's poorly focused, and maybe it's more of a cultural thing.
