Why are some states referred to as blue, red, or purple?
Calling a state blue, red or purple refers to the political party or parties voters in the state tend to support. The color blue refers to the Democratic Party, while the color red is associated with the Republican Party. Thus, a state that is blue is composed of a majority of voters that regularly vote Democratic. In a red state, the voters regularly vote Republican.
Purple states are states that are relatively equal parts Democratic and Republican. As a result of near equal representation, purple states are competitive. These states are often referred to as “swing states” or “battleground states” as an election is a toss-up and either party could win.
Have specific colors always been associated with each political party?
No, it is only since the 2000 election that blue and red have been associated with the Democratic and Republican parties, respectively. This color-coding system is now deeply ingrained in U.S. politics.
How did the color associations come to be?
Prior to television, Americans had to listen to the radio or read the newspaper to learn of election results. In some instances, newspapers used different shades of gray to create contrast and visually show election results on a map.
The invention of color television paved the way for color-coded maps. The first election to feature any color-coded maps was in 1972, but it was not until the next election four years later that they became standard practice.
Red and blue were often used because they provided greater contrast than colors like green and orange, and they were patriotic. At the time, there was no consistency and a lot of confusion as each television network used their own color schemes.
The lack of a standard approach meant that viewers might see Democrats in red on one channel and see them in blue on another. For example, in the 1980 presidential election, NBC used blue for Republicans and red for Democrats, while ABC used red for Republicans and blue for Democrats. This inconsistency persisted throughout the 1980s and the 1990s.
The turning point in solidifying blue for Democrats and red for Republicans occurred during the 2000 presidential election between George W. Bush and Al Gore.
How did blue for Democrats and red for Republicans become the standard?
The 2000 presidential election was highly contentious with unclear results for over a month due to extremely close counts and a recount in Florida. Two days after Election Day, the New York Times and USA Today, both nationally distributed papers published color-coded maps that used blue for the Democratic candidate (Gore) and red for the Republican candidate (Bush). These maps were then mirrored by other major news outlets.
While election coverage continued for the next month, Americans were repeatedly exposed to electoral maps cementing the color-party association into the public’s mind: blue for Democrats and red for Republicans.
After the 2000 election, the color scheme was widely adopted by the media, the political parties themselves, and the public further solidifying the association. The terms “red states” or “blue states” have become shorthand to describe a state’s political leaning.
What about other colors?
The Green Party, fittingly, is represented by the color green. The party, which emerged as a political entity in the mid-1990s, focuses on environmentalism and sustainability, topics that are heavily associated with the color green.
The color gold or yellow has become the adopted color of the Libertarian Party. While it is unclear exactly how this color association first developed, it could be that yellow is the third primary color with blue and red and Libertarians are often denoted as the de facto third party in elections. Another potential explanation is that it is the color of the ‘Don’t Tread on Me’ flag, popular among Libertarians, or that the golden yellow represents gold and wealth, since a founding principle of Libertarianism is a free market economy.
Do political color associations matter?
Yes and no. Colors carry significant cultural and psychological connotations. The colors suggest a unity within a party, a driving point that parties are a general umbrella and beliefs and issues are deeper than a color. The red-blue political color association is deeply embedded in the way elections are reported and understood by the public.
