I think Jeffrey is trying once again to hide the S word from the moderates. New Deal Democrats were Social Democrats. Socialism and even communism were pretty popular notions back then.
Capitalists had, after all, just caused a worldwide depression that led to WW2. Luckily the cold war came along and their propaganda machine was able to turn it all around and make it the fault of (you guessed it) Democrats, who are always communist sympathizers.
