Also, I remember reading a comparison between FDR's 16 points speech for the New Deal and the Communist manifesto. Twelve of FDR's goals were almost word for word from that manifesto. The conversion of the Democrat Party to the National Socialist Party was consolidated then (with the added bonus of having FDR becoming el Presidente for life). The New Deal also confirmed the trend of Republicans no longer resisting the DemoRats but instead, consolidating Dems Socialist gains and pre-empting Dem issues for Republican electability.
The DemoRat decline is not a recent event (much more gradual) nor is it close to a point where they will self-implode with faction fighting like the USSR's Communist Party. Unfortunately, the Republican Party doesn't offer much of an alternative. Socialism has been good to them.
