Johann Hari, writing in the U. K. Independent, considers how unreason took over the Republican Party. It’s a long article, but worth the 10 minutes it takes to read it. A nugget:
When this image was repudiated by a majority of Americans in a massive landslide, it simply didn’t compute. How could this have happened? How could the cry of “Drill, baby, drill” have been beaten by a supposedly big government black guy? So a streak that has always been there in the American right’s world-view – to deny reality, and argue against a demonic phantasm of their own creation – has swollen. Now it is all they can see.
