Republican Red - Democrat Blue

Why are Republican states shown as red and Democrat states shown as blue in election coverage? Why are some Democrats called Blue Dogs?

This explains Blue Dog Democrats:

No cite, but I always assumed news organizations selected red for the GOP to avoid the linkage between the Democratic Party and communism sometimes alleged by those on the right.

I remember it being reversed, at least for the 1976 election. Mostly I remember one of my college professors talking about the election night coverage in advance, telling us the colors, and making the connection dga mentioned. He was probably joking. At least, a little bit.

Maybe because it’s easier to remember that way: Red=Rep

I always assumed it was for mnemonic reasons as well. Red is for Republican.

I always assumed is was for DEMONIC reasons. The Devil is red…

My Congressman is a leader of the Blue Dog Democrats. My ex in-laws were yellow dog Democrats.
