Two elections took place November 8. Trump won 13 swing states as computed by Charlie Cook on his website by about 800,000 votes (Trump won 8 and Clinton won 5). But, he lost the popular vote in the remaining 37 states and D.C. by 3.7 million votes, leaving him behind by 2.9 million.
Democrats swept California by 61 percent, or more than 4 million votes. But their overflow voters in California was superfluous. The significant concentration of the Democrats in a handful of states led to the Electoral College failure and contributes to their weak position in the House of Representatives.
