It's up for debate, but it's a fact in the 1960s Democrats were carrying 90 percent of the Hispanic vote. Today they hoover around two-thirds.
I can't find the exact chart (probably due to Google-bombing since the election) but it showed that in 2012 that 70+ Hispanics were about 15% Republican, Boomers a bit more than them, Xers a bit more than Boomers, while the youngest Hispanics were about 31 percent Republican. That's still majority Democratic, but it shows a bad sign for the future. Hispanics are going to be more assimilated whether the far-right likes it or not, and when that happens they'll move onto new bogeymen.
A bad sign itself. Shouldn't he, after everything, have done abysmally worse?
