One graph in the story refered to in the previous post deserves to be highlighted since it puts in a nutshell not only the polarized nature of Congress, but the fact that members of Congress do not represent the interests of moderates, only those of the extreme - who happen to be primary voters by the way. This is based on data from California, but there is little reason to expect it to not apply elsewhere - here in Texas for example.
Notice that the no member of Congress lies directly under the peak of either the typical Republican or Democratic voter. This does suggest that we rethink who or what members of Congress actually represent. The traditional story - that they represent their constituents - clearly does not explain a thing.
The article this was pulled from costs money to access, but
here is a link to it anyway.
