A Twitter thread by Naval.

The two party system is an emergent "bug" in representative democracy.

A Political party is a coalition to monopolize the vote.

The framers of the constitution neglected to ban political parties, as it would infringe upon freedom of speech. So political parties monopolized the vote.

It is the nature of a winner-take-all system to consolidate down to two entities.

Any third-place party can always combine with the second-place party to become the new first-place party.

Therefore, our system can only represent two choices on any given topic.

The parties want to get as many voters as possible. The majority of voters are apathetic, not even playing the political game.

Scale effects rule the world around me. Including when it comes to branding, spreading messages, rallying resources.

The parties have to brand strongly as strongly as possible, to create the faithful core and to hook the apathetic. To make them play the game.

The two parties then are under selective pressure to evolve as far apart. If they drift towards the other party, then they risk creating apathy when they want passion.

Therefore, there’s no "middle ground party" in politics.

When you're on completely opposite sides of an issue, it's even easier to just talk about two different issues and call them the same thing.

On immigration, one party is talking about legal immigrants while the other party is talking about illegal immigrants.

On abortion, one party is talking about the definition of life while the other party is talking about self-sovereignty.
