Anyone remember how, before the year 2000, the U.S. party identifications of the colors red and blue were switched every four years by the TV networks’ electoral maps? The two colors only got locked in to their parties during the Bush / Gore endlessness, when people started talking about “red states” and “red America”, and so on
So if you wondered why the fascist party got socialist/revolutionary red, and the liberal-centrist party got Tory/royalist blue, that’s why. Pure historical accident
