Re: Power unchecked
"And there are defendable reasons for that."
Mmm, semi-defendable. There were contradictory motives (and some political maneuvers) in creating the Electoral College, and the evidence that it's a mishmash is, for example, demonstrated by the 12th Amendment to the Constitution.
Not that this excuses the Trump victory.
(Note, I'm not in favor of a strictly popular vote, but the Electoral College is a set of compromises that were unsatisfactory in the 18th century, never mind the 21st.)
