If I were a politician trying to win back independents, I’d say something like this: When I was a kid, I had a jigsaw puzzle of the U.S. Each state was a piece, and on it there was a drawing showing what people made there. California might have movies; Washington State, apples; New York, fashion or publishing. That puzzle represented an economy that was diverse and deeply rooted.

We’ve lost that. First Wall Street got disproportionately big, then Washington. It’s time to return to fundamentals. No short-term fixes. Government should do what it’s supposed to do: schools, roads, basic research. It should not be picking C.E.O.’s or setting pay or fizzing up the economy with more debt. It should give people the tools to compete, not rig the competition. Lines of restraint have dissolved, and they need to be restored.

Independents support the party that seems most likely to establish a frame of stability and order, within which they can lead their lives. They can’t always articulate what they want, but they withdraw from any party that threatens turmoil and risk. As always, they’re looking for a safe pair of hands.
