Remember that Hitler's rise to power was supported in no small part by his promise — which he kept — to put the German people back to work.
If the right-wing and Republican party can successfully merge the eliminationist narrative of purity — we must purge the corruption of liberalism and socialism and restore our pure American values — with the story that the Republicans can succeed in putting America back to work where the Democrats have failed, they will win handily in 2010 and 2012. The Republicans await only the emergence of a leader as disciplined, focused, and most importantly pitiless as Hitler. They lack only the will, not the opportunity.
Remember too that Hitler did not have a majority of popular support, but his minority was, like him, disciplined, focused and ready to do what was necessary. The Christian fascists are just as disciplined, just as focused, and just as ready to do the job, however dirty. They lack only leadership.
