I may be wrong...but I seem to recall that, a decade or so back, the MSM had the Dems. as RED and the GOP as BLUE on their maps. I guess the use of red for the Communists was hitting too close to home.
If I’m recalling this incorrectly...never mind and go about your business.
Your memory (and analysis, IMO) is in great shape.
The change was made to confuse people and to label conservatives as the bomb throwing radicals. I refuse to use the terms as presently sanctioned by the Left.
Part of Left tactics is to confuse the language so that only the Left can communicate. Words mean what the Left deems them to mean and meanings change often so that people thinking they have a certain opinion about something find out they, according to the Left (including MSM), are credited with an opposite opinion.
USA Today flipped the paradigm with its county-by-county map of the 2000 presidential election vote.
