National politics in healthy periods is not about “difference,” it is about commonality. And it will be dominated by whoever best captures Americans’ imaginations about our shared destiny. Ronald Reagan did that very skillfully, whatever one may think of his vision. So did Bill Clinton, who took a page from Reagan’s playbook. He seized the Democratic Party away from its identity-conscious wing, concentrated his energies on domestic programs that would benefit everyone (like national health insurance) and defined America’s role in the post-1989 world. By remaining in office for two terms, he was then able to accomplish much for different groups in the Democratic coalition. Identity politics, by contrast, is largely expressive, not persuasive. Which is why it never wins elections — but can lose them.
