 Does it surprise you to hear our political system characterized as an industry? It surprised this guy. Absolutely never thought of it in those terms. And that's Michael Porter, the world-famous business strategist. And at the core of it is what we call the duopoly. Comparing our political system to something like Coke and Pepsi? That can't be right, can it? No, Porter says. It's worse than that. Coke and Pepsi don't control their market nearly as fully as the Republicans and Democrats do.
