Left, Right and Ideology in American Politics
"Republicans have moved further to the right than Democrats to the left in the contemporary period."
"President Obama is the most moderate Democratic president since the end of World War II, while President George W. Bush was the most conservative president in the post-war era."
Those are two conclusions in this series of brief blog posts    by political scientist Keith Poole - who, I think it is fair to say is himself hardly anything resembling a liberal politically. Keith studies this sort of thing for a living. So, if you are searching for the source of our current political stalemates please look to the right. And when the red-staters try to paint Obama as a socialist or a radical the proper response is to laugh heartily and recommend clinical help.
