Political Memes

I don't believe this. People may have multiple agendas. They may hate foreigners or cultures, but people's allegiances are always first and foremost to their own, to keep living in the most comfortable way they can with the lowest possible eftort. It's kind of game theoretical in some sense.

Game theory occupies itself with the adversary roles of generosity (a moral principle) and calculation (a purely rational one), and in some way you could say that in a system which only allows one of two outcomes, a lot of assumptions are subsumed under those two separate outcomes.

What if Candidate A is for lower taxes, higher immigration and Candidate B is for higher taxes and lower immigration?

What if both candidates agree on lower taxes and lower immigration, but one of them also proposes reinstating slavery, and the other one wants none of it but instead mandatory abortions?

In a two party state you don't get enough fine grained resolution to deal with problems that require any complexity beyond perfectly white and perfectly black.
