Trump Signal Index
CNN analyst Harry Enten published a polling breakdown this week that he says made him re-examine his own spreadsheet. In late 2024, Trump held a 9-point advantage over Kamala Harris among independent voters on the question of who they trusted more on inflation. By May 2026 — fifteen months into Trump's second term — that number has collapsed to negative 70 points among the same group. A 79-point swing.
"Honestly, I was so worried I made a typo that I went back and looked at the spreadsheet again," Enten said. "My God, to see numbers this bad with independents — that's really what the president's standing on inflation looks like right now."
Why Independents Are the Number That Matters
Trump's base has not moved. Republican voters still back him on economic management by wide margins. The collapse is concentrated among independents — the voters who determined both his 2024 victory margin and who will determine his party's 2026 midterm exposure.
Independent voters chose Trump in 2024 in part because they trusted him to manage prices better than the Biden-Harris administration had. That trust was the core of his economic mandate. A minus-70 rating among the same group is not political turbulence. It is the mandate collapsing.
The 79-point swing from plus-9 to minus-70 is not the product of any single event. It reflects cumulative frustration with prices that have not come down combined with new sources of inflation — tariffs, energy costs — that independent voters are now attributing directly to Trump's policy choices.
Independents don't typically swing 79 points on a single issue in 15 months. The scale of this shift reflects not just dissatisfaction but a full reversal of the core premise on which they voted for Trump: that he would be better on prices. When a mandate reverses this completely, it limits what a president can do politically — because the permission structure that enabled bold action has eroded.
The Iran War's Direct Role
A separate poll cited in Enten's analysis finds that 73% of independent voters blame Trump for recent gasoline price increases — 53% saying "a great deal" and 20% "somewhat." That attribution matters because gasoline is the inflation variable that independent voters feel most viscerally.
The Iran War's primary domestic economic effect has been oil. The Hormuz blockade reduced global supply. Brent crude moved from approximately $82 at the start of the conflict to over $120 at peak. US retail gasoline prices followed. Drivers filling their tanks in the spring of 2026 are paying materially more than they were when Trump took office in January 2025.
Trump's argument that the war is necessary to prevent Iranian nuclear weapons does not translate into relief at the pump. Independent voters are capable of believing both that the policy rationale is real and that they are personally bearing the cost. They are doing exactly that — and they are assigning the cost to Trump.
The Political Arithmetic of $120 Oil
Trump's original economic coalition held together on the expectation that his second term would mean cheaper energy, lower costs, and a reversal of the inflation that characterized Biden's years. The Iran War has inverted that expectation on energy specifically — the one input that affects every other price in the economy through transportation and production costs.
A ceasefire that brings oil back toward $80 would begin to repair the gasoline price grievance. But the political damage from a year of elevated prices does not reverse immediately when prices fall. Voters remember the high-price period. They recalibrate their trust more slowly than prices move.
The timing matters: the 2026 midterms are approximately five months away. If the Hormuz dispute is resolved before summer and gasoline prices begin declining by July, the political window for recovery exists — narrow, but real. If the conflict extends through summer driving season at current oil prices, the independent voter damage compounds further before any votes are cast.
What the Poll Tells Markets
Approval ratings are a lagging political indicator, but they are a leading indicator for policy constraint. A president at minus-70 with independent voters on inflation is a president whose political room to absorb further economic pain has narrowed significantly.
That constraint has a market implication: Trump needs the Iran deal more than the raw military math suggests. A ceasefire that brings oil down is not just a foreign policy win — it is the primary mechanism available to him for rebuilding the economic credibility that the independent voter data shows has collapsed.
The urgency of the May 14 deadline is therefore not purely about the Beijing summit optics. It is about whether Trump can deliver a price-lowering event before the midterm window closes.
