I think that today is very interesting in that a lot of the R neocons of yesteryear have shifted to D neolibs today. It's really weird in a lot of ways.

Note: I've been pretty heavily libertarian minded for a long time, so this observation has mostly been an outside perspective even though I'm currently more inclined to move R as a secondary/pragmatic position. There are some aspects of R and D I'm inclined to support.
