Means the Nevada poll is pretty questionable.
Actually not. It seems the poll was weighted according to 2012 exit polls, with 19% Hispanics.
And they back Clinton over Trump by a lot ...
Amd they'd back her even more overwhelmingly if there was a spanish language choice.
Not necessarily. If anything, Hillary is undervalued by 2-3% at best because both she and Trump have 100% name recognition, even among Latinos. It simply doesn't matter if you ask "are you voting for Clinton or Trump ?" or the Spanish version of it because they are known to everyone.
