You can argue equally well that Clinton won the electoral college except for Wyoming, North Dakota, Alaska, South Dakota, Montana, Idaho, West Virginia, Kansas, Utah, Arkansas, Mississippi, Iowa, Oklahoma, Kentucky, Louisiana and South Carolina. That excludes about the same number of people as your argument, and is equally silly.
He won by 80,000 votes in 3 states. That's how the EC works. Holding up California, our richest state, as unwelcome is un-american as most of Trump's actions. Why do Trump supporters hate our most successful state yet somehow give free passes to southern hellholes that have little more than dying towns and meth addiction specialists. Its extremely dismissive of millions of votes and the difference between Trump and Clinton is the largest in history for an EC upset. That should worry people. Invalidating 3m voters in any other country would be something the US would criticize. When it happens here its shrugged away with dismissive attitudes by Trump supporters who refuse to see a problem. Of course, if their guy lost the EC and won the popular vote, they'd be singing a different tune.
