Pantone Cage Fight
So everyone is geared up for the big Red State - Blue State matchup this coming Tuesday. I guess you need to be a bit older to realize just how screwey that color scheme is. If you go back in time it was almost always that Republicans were most commonly represented in blue and, if anything, Democrats were red. Don't believe me. Even today if you check out the map references that date back a few years you will see. Take for example all the maps on David Leip's Political Atlas site. Do those maps look backwards to you? Or are all the maps since 2000 backwards? Or the more ominous classification that red is always hostile. I guess that matches what half the US thinks these days, but still.
results of the 2000 presidential election. It may not have seemed seminal, but it was a striking map because it was binary (just red or blue, winner take all) and at the county level. It was arguably misleading (see paper references at bottom for more on that) given the variation in population density across the nation.. a variation that has a much bigger impact when graphed at the county level, vs. the the normally presented state level. When it comes to maps having impacts though, not many top it to this day.
Elephants Are Red, Donkeys Are Blue
There is a real story here.. and it all gets to how media has changed. It turns out that because the color was so important, it could potentially influence the outcome. The best explanation out there is that prior to 2000, the major media networks stuck to a scheme whereby the incument party alternated between red and blue in their graphics with each election cycle. Think about that. Since color mattered someone must have decided it was not fair to always have one party blue and the other red. It wasn't even fair to always have the incumbent party the same color. If that is the full answer, it means that there was a much higher level attention paid to being keeping the presentation objective. It also means that in 2000 it was just the turn of the cycle that Republicans came up red, nothing more. But the punditocracy didn't seem to get the memo on the itinerant nature of the color system and cemented in place the taxonomy of color that has now skipped into the cultural awareness of all things political.
If all that leaves you wanting more.. or think that is all too superficial... here is a Princeton working paper for you: On Graphical Representations of Voting Results
