Momentum. Keep the story moving, and don’t stop to have a discussion about politics every scene. You should definitely talk about the game when you take a break or when you finish the session, but keep the pace up during play. The system is designed to quickly transition the players from one scene to the next — that’s what the rigid scene categories are for, so that you don’t have to think too much about what comes next — and you should lean on that system. When you keep playing, when you press forward with a new plan and a new ideal to follow, that’s when you’ll find yourself in the most compelling political situations and well outside your comfort zone. That’s when you’ll stop for a bathroom break and find yourself staring in the mirror asking: “What did I just do!?”
If you’re worried that sounds too artificial, take a moment and think about politics today. How long-term do you think those politicians are planning? I mean, really planning? Yeah, I thought so too. Let the system transport you into that same mindset for an evening.
