Here's a very nice chart from Digby. She uses it to make a very worthwhile point, but I want to use it for another purpose:
That's the historical pattern in this country, and if the Republicans go the way of the Whigs, in the end it will be because of this. They will not protect us from economic disaster if it stands in the way of the rich further enriching themselves, and so they doom us to endless depressions or brushes with depression.
I have long argued that the only thing which distinguished the Great Depression from what happened in 2008 is that, when the market collapsed in 1929, Republicans had over three years- until FDR's inauguration in March of 1933- to continue wrecking the economy, while luckily for us, this time we only had to wait three and a half months before responsible leaders (i.e. Democrats) could take over. In both cases, economic recovery began very quickly, but the country was in a far bigger Republican generated hole in 1933.
