This is, in a strict constitutional sense, as it should be. It was really no more than wishful thinking to imagine the Electoral College reversing its clear majority, regardless of its disparity with the popular vote.
Much was made, including by yours truly, of the purported role of the Electoral College in preventing an incompetent demagogue under the influence of a foreign power (to take a random example) from ascending to the Presidency. We took as our text Federalist 68, in which Hamilton touted the possibility of the Electoral College taking such action.
The only problem with this is kind of a big one: it's not really laid out in the Constitution like that. We have to remember that the Federalist Papers, as brilliant a set of political treatises as they are, were published primarily as sales brochures for the attention of the New York constitutional convention, and are not an "official" interpretation of the Constitution's intent.
Even Hamilton hedged on this. After describing the possibility of the Electoral College taking such action, he more or less said "Sure, but that won't happen because AMERICA, amirite?" I am paraphrasing.
Bottom line: the system worked as intended; it's just that the system's foundation is flawed. Three-fifths of a cheer for the Electoral College.
