Blue has throughout history been associated with conservatism.
The media in the USA inverted that several years ago in an attempt to distance your DemocRats from the communistic direction their leadership has taken.
Red state/blue state is upside down.
Since red is my favorite color I am not complaining! Although I grew up on the tail end of the Cold war I recognize the historical significance of that color, and can understand why some do not want to use Red=Conservative.
To me this color= passion,= winning, =victory, but meh.
Ain’t media propaganda grand ?
I won’t use that blue = Democrat crap. I’m a blue Republican, and unapologetically so. I’m not a Communist Red.
