The states which encourage baby-killing should be blood red.
I have a pet theory, which others have attempted to shoot down in various discussions (not necessarily here, though it could have been here too), that the MSM assigned blue to liberals and red to conservatives because blue has mainly benign connotations, while red has many negative connotations.
Blue signifies calmness, peace, tranquility, coolness, rationality, and even though I doubt this was in their minds, is the color often associated with Our Lady. (It is also a color commonly associated with Israel, and we are all surely expected to love Israel and to say she can do no wrong.)
Red signifies agitation, heat, blood, fire, fury, hatred, irrationality, revolution, disharmony, anarchy, and is commonly associated with Satan. It is also the trademark color of Communism, just think of the flags of the Soviet Union and China.
IOW, blue good, red bad.
The political color map should be the other way around.
