It’s clear that you only dislike the Electoral College now only because your nominee did not win. There is no question nor doubt to who won the election fairly, both nominee’s knew what was required to win and both played their strengths as well as they could.
I also strenuously object to the idea of conscientious electors in 99% of cases and this is one of them. To vote against the will of the people you represent is one of the most dangerous things you can do, no matter how noble you think you are being.
I would also remind you that if we went purely by Popular Vote that Obama would have lost the Democratic Nomination to Hillary Clinton in 2008.
