From Krugman,
There’s Something About Money
The republican mind doesn't understand much of anything. How many of the "Simple People" understand ISLM or have even heard of Hicks?
So what good is the republican mind? The republican mind does provide a type of comedy not found anywhere else. Where else can you find out that: QE drives the stock market, emerging markets are doomed with the end of QE, guns reduce crime, Reagan was for low taxes, smaller govt, etc..., Keynes is scam (LOL!), the big blogs say 1 million jobs were lost in a month, inflation is running at double digits, CO2 causes cooling, coal jobs didn't return because of Obama (no mention of natural gas), Benghazi!, FDR wanted to privatize social security, etc.......
You can criticize the republican mind but not too much; you don't want to discourage them from writing or talking!
