The reversing of the traditional meanings of `red' and `blue' was intentionally perpetrated by the MSM during the 1980 presidential election, to make the conquering tide of Republican victories across the U.S. appear sinister. The tactic has been employed ever since to separate the color red from those who should be known as Reds or Red sympathizers.
Down south, we embrace the notion of `red states' as those with a high content of red clay in the soil.
