Truth:
In every election including 2000, the incumbent candidate or candidate's party was shown in blue while the challenging candidate/party was shown in red. This is a convention taken from military battle maps where USFOR and allies' positions and movements are shown in blue while OPFOR is shown in red.*
Thus is was that in 2000, Gore/Lieberman states were shown in the blue of incumbency (the incumbent, Bill Clinton, term-limited but still in office) while Bush/Cheney states were shown in red.
If the pattern continued (and I honestly don't know if it did), during the TV coverage of the 2004 elections the Bush/Gore states should have been displayed in blue and the Kerry/Edwards states in red. The wikipedia entry shows it the other way
http://en.wikipedia.org/wiki/United_States_presidential_election,_2004I think we are stuck with the current color pattern until something else accepted by the general public, and any protest to the contrary is as futile as shouting
"Photocopy! photocopy! photocopy! Xerox is a BRAND NAME!" --or, since Aspirin was also once a brand name, insisting on calling it acetylsalicylic acid.
*During the Soviet era, Soviet and Warsaw pact nations flipped the concept, showing Communist forces-- themselves-- in red and their OPFOR in blue.
