My theory is that any hegemons (lacking significant exterior scapegoat possibilities) sooner or later divide into factions.
When I was growing up in the States, there was a significant overlap between the left R wing and the right D wing. Since I left the Old Country, it seems (from afar) like that overlap has disappeared, and maybe there's even unoccupied space where the middle used to be.
