US politics may have its honourable moments defined by people with the highest ideals and driven by heartfelt emotions but Wednesday’s Republican debate is probably not going to be one of those instances. We can talk about ideology, geopolitics, economics, the environment, AI’s role in the free market, the worldwide clamour for limited resources, and any number of “important” topics (guns!), but, on another level, politics amounts to calculations as crude as whether an obese seventy-seven-year-old might succumb to an overly spicy taco bowl.
