538 had a nice article summarizing our report on their weekly polling/political data roundup. Well done, and they note the following, which is correct:
"[T]his study underlines two broad truths in today’s U.S. politics. The Democrats need to do a better job wooing white working-class voters and getting more blacks to the polls (black populations are larger than Asian or Latino ones in states like Michigan and Ohio that have a lot of Electoral College votes). If they don’t, they’ll have a problem winning states in the middle of the country and therefore the Electoral College. At the same time, Republicans have a huge problem with non-white voters that imperils their ability to win national elections and should not be ignored because of Trump’s victory in 2016.
The authors of this study, in looking at the parties’ demographic coalitions, wrote that “quite a few future scenarios could mimic the result of the 2016 election — a Democratic win in the popular vote with a Republican win in the Electoral College.” That is really bad news for Democrats, but hardly a great place for the GOP to be in either: trying to lead a country where a plurality of voters voted for the other party."
