For most of my 25 years in public affairs, the work has rested on a quiet assumption: that somewhere in the middle of the American electorate sits a population of persuadable people, and that a thoughtful campaign—built on credible voices, sound data and accurate framing—can move them. That assumption has shaped how we design coalitions, how we counsel clients and how we measure whether the time and money were well spent.
APCO recently hosted Charlie Cook of The Cook Political Report for a conversation I had the privilege of moderating. Charlie has been forecasting American elections for four decades. He is the closest thing our political class has to an honest umpire. He calls balls and strikes the same way regardless of who is at the plate, and his diagnoses tend to land before the rest of us notice the symptoms.
The picture he drew deserves attention from all voters and particularly for anyone that builds advocacy for a living.
The Narrowing Playing Field
About 95% of self-identified Democrats vote for Democratic candidates. About 95% of self-identified Republicans vote for Republican candidates. Those numbers have held across the last three presidential elections. The slice of true independents—voters who do not lean reliably one direction or the other—is around 10% of the electorate, sometimes less. And what those voters mostly do, Cook argues, is punish whichever party disappointed them most recently. They are less an audience to persuade than a thermostat to read.
The narrowing extends to the playing field. Only one Republican senator sits in a state that leans Democratic. There are no Democratic senators in states that lean Republican. The number of genuinely competitive House districts is the smallest it has been in living memory. Issues that once cut across party lines now sort cleanly with party identity, which means individual issues themselves move fewer votes than they once did. If you know whether a voter is a Democrat or a Republican, you can guess where they stand on almost everything else.
This is not a story about who wins in 2026 or 2028. It is a story about the shape of the field on which all of us—companies, coalitions, advocates, journalists and public servants—now operate.
Cook offered a deeper observation that connects the dots. He said we stopped teaching civics effectively in this country roughly 50 years ago, and the consequences are visible everywhere. People are no longer taught why the Senate was designed not to be representative. Why six-year terms were chosen to insulate senators from the immediate passions of the voters. Why the filibuster exists. Why power was separated into three coequal branches calibrated to check one another. Why certain powers were reserved for the states and others for the national government. These were not arbitrary procedural choices. They were part of a careful architecture, designed to make compromise the price of governing. Incorporated to prevent abuses that we had experienced in the past or could in the future.
When citizens lose the vocabulary of those institutions, they also lose patience for the work the institutions were designed to do. Compromise begins to look like weakness rather than oxygen. Procedural protections look like obstruction rather than ballast. The line between durable policy and political payback gets harder to draw.
Intensity and Durability
What does this mean for those of us in advocacy and public affairs?
It changes both the math and the craft. When persuadable voters are scarce, persuasion campaigns yield less than they once did. Intensity—whether your supporters show up, whether your opponents stay home or whether your coalition holds when the temperature rises—becomes a more important currency than the elusive middle. Strategies built on cross-pressured voters responding to good arguments need to be paired with strategies that mobilize the people already inclined to act.
It also raises the bar on coalition durability. Eleven of the 13 federal elections this century have flipped at least one branch of government. Five consecutive presidents have walked into office with both chambers in their party’s hands and walked out with neither. In that volatility, the policy goals worth fighting for are the ones whose coalitions can survive the next swing of the thermostat. Single-cycle wins that depend on a particular majority rarely last.
There is one more thing to say. The civics deficit Cook identified is not the problem of one party or one administration. It is everyone’s problem. If the architecture of the republic is no longer broadly understood, the institutions will not defend themselves. They will erode quietly until something we depend on stops working. Public affairs, properly understood, has always been more than a service offered to clients. It is a stewardship of the spaces in which serious decisions get made.
That is the work, and it has not gotten easier. It has, if anything, gotten more important.
