Who is the colorblind nation here?
I understand that the coulours used to swap over in the states before every election and then one time they just got stuck the wrong way round
"I want to be the guy for people with pickup trucks and confederation flags."
This in part because both major political parties use red-white-and-blue as their color scheme (which actually tells you a fair bit about American politics and is suggestive of the differences -- or lack thereof -- between the two major parties). Thus neither party has a "natural" color that distinguishes it from the other.
However, entirely by chance AFAIK, the networks were using red as the Republican color and blue as the Democratic color on election night in 2000. The long, drawn-out drama of that night has, for the moment at least, turned red into the Republican color and blue into the Democratic color.
I must say I have no idea how the switch occurred by it has to be the result of decision made by the three major television channels. Red=REpublican? Ein Land ist nicht nur das, was es tut -- es ist auch das, was es verträgt, was es duldet.
