Their behavior makes sense IF you assume that the real objective of the Republican Establishment is to maintain the PRETENSE of there being actual opposition to Socialism.
In other words, the Democrat Leadership and the Republican Leadership are just a matching pair of sock-puppets for the Ruling Class.
As long as the Republican Leadership maintains just a pretense, without reality, then they can engage in graft, get invited to the best parties, sleep with cute lobbyists, etc, and the press will not "notice". The nightmare for the Ruling Class, though, is if the "bought" Republicans get replaced by Tea Party candidates who might rock the boat.
I couldn’t have said it better!
Thanks!
