nevada may be an outlier because of mexican american turnout (arizona and colorado should show a similar trend, but it wouldn't necessarily be enough to matter in other states), because of reid's political organization and because legalizing marijuana was on the ballot, potentially turning out voters interested in voting on that issue that would not have otherwise voted.
that said, it does look like you are seeing something of a similar trend in hispanic vote turnout in florida, georgia and north carolina. in the upper midwest states you are seeing an opposing trend with heavier than expected white turnout.
as i understand it, however, nevada is the only state where it is possible to both get the detailed data on who and where turnout is coming from and that hasn't changed early voting laws from 2012. so there are more complications and limitation in interpreting data from other states.
