The astounding advantage the Electoral College gives to Republicans, in one chart
The study, by three economics researchers at the University of Texas, quantifies just how often the Electoral College will produce an inversion that is, an election where one candidate wins the popular vote but the other walks away with the presidency. The numbers are simply astonishing.
In modern elections where one party prevails by just 2 points in the two-party popular vote, inversions are expected in more than 30% of elections. That number rises to 40 percent in elections with a 1 percentage-point margin.
Republicans, moreover, are far more likely to benefit from an inversion than Democrats. In the modern period, the study suggests, Republicans should be expected to win 65% of Presidential contests in which they narrowly lose the popular vote.
