Why Trump Had an Edge in the Electoral College

… The Electoral College’s (largely) winner-take-all design gives a lot of weight to battleground states. Mr. Trump had an advantage in the traditional battlegrounds because most are whiter and less educated than the country as a whole.

But Mr. Trump’s success in those states isn’t just about demographics. It’s about quirks of history, like the outcome of a battle over Toledo, Ohio. It’s about gains by Mrs. Clinton that went unrewarded. It’s also about plain luck. CONT.
