What about today's Republican Party?
Let me give a stream-of-consciousness-personal-psychodrama-confessional-oversharing answer to that question:
I am not a political scientist. I am not an especially deep student of politics.
My government experience came from working in 1993-1995 in Lloyd Bentsen's Treasury Department, when he had just gone from being senator from Texas and chairman of the Senate Finance Committee Treasury Secretary. He and his staff, broadly, believed that what you did in order to govern--with a kinder and gentler, technocratic, equitable-growth approach to policy--was to start with a centrist block, Bentsen and his friends and allies, people from Jack Danforth on the right to Daniel Patrick Moynihan on the left. You would then call for bids from the left and right. You would ally with whichever was willing to give you better deal to build a majority. And you would then vote your bill out of the Senate Finance Committee 12-5 and roll it through initial passage, conference, and presidential signature.
