Agree with the question, what are the beliefs of the middle? Are conservatives more or less conservative that 30 years ago? I say far less. Where is the left compared to 30 years ago? Much farther left. So just what ground is there for the middle? The division between conservatives and the left is no longer policy, it is constitutional. How does that split work? That is the crux of the election
I made a comment in some other thread (I think) that the political spectrum is no longer a standard bell curve and that the "bell" has shifted to the left.
