From what I understand the networks switched colors ever Presidential election year. The whole Red vs. Blue was due to the geographical concentrations one saw in the Bush I 2002 election. I guess the name stuck and the networks stopped switching colors.
The Rats are communist to the core and know about the color red, so they used the well worn trick of using, saying, etc... the opposite of what they are to deflect attention.
With the media's help they switched the colors as a pshycological ploy to try to pin what red connotes with the GOP.
Of course, we know red is for communism...when in fact, red is for blood...RED stands for the blood of JESUS...
The colors used were started when color television was starting to take hold. Traditionally (but not always) CBS and NBC used blue as the party in power and red as the party out of power. There were exceptions to this rule (like 1968 when ABC used green and yellow to represent the Democrats and Republicans).
In 2000, the internet was really starting to take off and many online commentators and bloggers started referring to “Blue States” (meaning States leaning towards Gore) and “Red States” (meaning States leaning towards Bush).
The parlance of the 2000 campaign stuck and that’s why Democrats are now “Blue” and Republicans are now “Red”.
