First, I did not go to the link, I am responding to what you felt obligated to copy/paste.
This section of the opinion piece is literally only crying that certain parts of the Constitution are the only reason that the GOP has any influence at all, and I would speculate that he would like to get rid of the Electoral College.
This country has never been majority rule.
I'm sure that Chris could give us a much better dissertation, but as I recall, there were two houses so that overwhelmingly populated states could not be in complete control simply because they had the most seats, so we get the House and the Senate. The Senate was initially supposed to represent the states, and that went away because the states were stupid, would not fill their seats as required, and then we decided to let the people vote for Senators instead, which kind of screwed up that house of Congress, in my opinion, but it is what it is at this point. The Electoral College is the same mechanism, in an attempt to make sure that the flyover states still matter come election time. The irony in the third paragraph is probably lost on you and the writer.
I am guessing that s/he was not one of the liberal writers who were begging the Electoral College to vote Hillary in anyway as some sort of conscientious objector because Trump was Trump? Honest question, since I would think taking this opinion on ridding us of something that s/he was willing to use when it could have helped their cause would greatly weaken the opinion.
