American politics has an age problem. At least, that’s what voters think. According to a new New York Times/Siena College poll, 33 percent of Democrats who want a different candidate for president in 2024 pointed to Joe Biden’s age as a motivating factor. But a nearly equal percentage say they aren’t keen to have Biden for a second term because of his job performance — or lack thereof. Could the answer to appease voters be that Democrats just need some young blood? Or is there a deeper rift between voters — especially young ones — and political leadership? Jane Coaston brings together Michelle Cottle, a Times editorial board member, and David Brooks, an Opinion columnist, to parse out what we are really talking about when we talk about age in politics. “What is age actually a proxy for?” Cottle asks. “Is it your concerns about fading ability, or is it concerns about a lack of fighting spirit?” But for Brooks, the question is centered more on stagnancy: “Why has the gerontocracy been able to stay in power? What is it about these people that they’ve been able to persevere and just stick around?”
