The three party system

John Quiggin explains The three party system.

Looking at the way politics has evolved over the past 25 years or so, in the English-speaking world and beyond, I have developed an analysis which is certainly not original, but which I haven’t seen set down in exactly the way I would like. Here’s the shorter version:

There are three major political forces in contemporary politics in developed countries: tribalism, neoliberalism and leftism (defined in more detail below). Until recently, the party system involved competition between different versions of neoliberalism. Since the Global Financial Crisis, neoliberals have remained in power almost everywhere, but can no longer command the electoral support needed to marginalise both tribalists and leftists at the same time. So, we are seeing the emergence of a three-party system, which is inherently unstable because of the Condorcet problem and for other reasons.
