If you want to hear progressives screaming just get a few states with Republicans in control of the legislature and which have massive dem voter fraud in large cities to change from winner take all to dividing up the electoral votes according to the percentages.
Yes, when the GOP does it it's called "gaming the system." Not until the closing paragraph is there an acknowledgement that just such a system is already used in Maine and Nebraska. I guarantee that if Texas were to propose such system the left would be effusive in its support.
