A few scattered thoughts.
First, regarding the "surge" it looks like Trump, at this point, received fewer votes than either John McCain or Mitt Romney (or Hillary Clinton for that matter). Even an aggressive deportation/labor camp policy cannot alter long-term demographics.
Unfortunately, the EC yet again favored the Republican. Four years ago Donald Trump was saying the EC was a "disaster for democracy." I always hope the Republican will win the popular vote, but only garner a minority of electoral votes. While perhaps optimistic, I still think the Electoral College could offer future advantages to Democrats.
As for the Skeptic Tanks of the world talking about white people, I see a problem there as well. According to the exit polls (if we believe the exit polls), Romney won a bigger percentage of the white vote than Trump. Trump outperformed Romney when it came to all minorities (Blacks, Latinos, Asians). Now one could say the white people voting for Trump were motivated by white identity politics.
Trump did one percentage point better with men than Romney did against Obama (and slightly worse with women), but perhaps men made up a larger share of the electorate in this cycle.
