One other thing: Trump got about the same fraction of the Latino vote as Romney in 2012 and McCain in 2008, to within exit poll survey error. The actual cited number for him is between those for McCain and Romney. See http://www.pewresearch.org/fact-tank/2016/11/09/hillary-clin...

So apparently he's no more abnormal than McCain and Romney were, to those voters. Or at least they felt their other options this time were a lot worse. Or something. It's hard to draw a hard conclusion from the numbers here.
