Did Democrats Get Lucky in the Electoral College?

… Liberals tend to cluster in dense urban centers, creating [congressional] districts in which Democrats might earn as much as 80 or 90 percent of the vote. In contrast, even the most conservative districts in the country tend not to give more than about 70 or 75 percent of their vote to Republicans. This means that Democrats have more wasted votes in the cities than Republicans do in the countryside, depriving Democrats of votes at the margin in swing districts. Eliminating partisan gerrymandering would reduce the G.O.P.’s advantage in the House but not eliminate it.

But if this geographic principle holds true for the House, why doesn’t the same apply for the Electoral College? [cont.]
