It was a simplified example to explain the game theory behind it. Abortion/deficits is a result of that. You find (or create) wedge issues that act as an issue that voters won’t budge on, thereby deciding their vote. If 50% or more of the population feels strongly enough about a given issue that they will always vote based on it then you position yourself as the party that supports that issue and you have a guaranteed win. I don’t like the system, just explaining that those are the incentives that the rules create.
