That lead isn't as large as the other polls have shown, but it was taken during the RNC, and if Hillary does win by that much, it'll probably be enough for her to win.
This is a poll of Latinos from battleground states. So it takes out favorable states like California, New York, New Jersey, Illinois (and slightly unfavorable in Texas) for Clinton. So it makes sense that it would be a bit narrower.
I would think New York would be less favorable. I don't know enough about Texas, but my guess there would be more favorable (unless "White Hispanic" is higher than I'm expecting). I don't see presidential year crosstabs for these very often though so there's some guesswork.
NY Latinos tend to be extremely Dem even in normal times. Few Cubans, mostly Dominicans and Puerto Ricans - both groups have always voted more like Blacks than like Hispanics, at least in NY. I mean, look at East Harlem.
Texas Latinos are a mixed bag. And Texas Republicans have been doing relatively good with some of them.
