Yes, the Electoral College is antidemocratic (both capital and small “d”) and should be abolished, but that doesn’t address the problem cited in the article. The Electoral College only biases the results in favor of less-populated states relative to larger ones, because of the extra two votes awarded to each state corresponding to its two senators. With or without it, rigged election boards can still manipulate or refuse to certify the popular vote in their state if they don’t like the outcome.
And in what reality were the Republicans ever the “party of the working class”? Not since Teddy Roosevelt’s day.
