"78,000 votes is nothing" - because they were the wrong people voting for the wrong candidate! De-platform them from the voting booth!Oh sure, 78,000 people pulled the lever in the wrong direction by mistake, what a stroke of luck for God Emperor of the Multiverse Donald J. Bl*mpf.
"the Dem in the race got 3m more votes" - for the millionth time: Hilary Clinton was exactly the kind of candidate the Electoral College was designed to frustrate. She ran up her majority in concentrated urban areas on the coasts, which the Founders explicitly wanted to avoid as a danger to national unity.
Her loss was not a freak accident. It was not a bug, it was a feature. The EC addresses a specific problem, jettisoning it leaves that problem unsolved, and all these EC replacement movements are short-sighted whiners who can't handle thinking about systems instead of their own personal angst.

If you don't like her loss, blame the entire Democratic party for being idiots and running an EC-hampered candidate in an EC system.
