Very informative thread so far I must say, I have a question, why is the "other" share of the electorate double so far what it was in 2014, 12% vs 6%, surely Hispanic population growth is not that rapid, is it just White and Black voters being identified as other.
I believe it's that voters can now decline to specify a race when registering, which wasn't always true. So previously "others" were actually other groups, but now it includes other groups plus unspecified. (Adam, please correct me if this is wrong.)
This makes sense, especially considering how the other vote was mapped two pages ago. It definitely looked like a a map of 'new' voters, which is why the map correlates so well with Clinton - it's where Dems have been focused on registration.
