Democrats Won Big on the Economy They Can't Fix

Voters just handed Democrats their largest House majority in nearly four decades and their biggest Senate edge since 2008 — on the strength of an affordability anger they will struggle to relieve. That's the core paradox economist-watchers need to sit with after Tuesday's election, laid out by Eduardo Porter, the economics and politics journalist who writes the Being There newsletter on Substack.

"It was the economy, again," Porter writes. Voters' acute concerns over the rising cost of living fueled what is likely to be the biggest swing toward Democrats since Watergate, even as Donald Trump largely ignored the issue.

What does the win actually change for Democrats?

Very little, in practical terms, over the next two years. The new majority came to power promising to restore affordability on pricey gas and groceries, exorbitant mortgages and unaffordable healthcare. The affordability strains that delivered Democrats their majority are, Porter notes, not dissimilar to those that delivered the presidency to Trump two years ago — and could quickly become the new majority's enemy.

The incoming leadership has already staked its brand on the promise. "First, Americans want Washington to bring down the cost of living," said Chuck Schumer, the Senate majority leader-in-waiting. Likely House speaker Hakeem Jeffries added: "we've promised to fight for an affordable America, and that's exactly what we will do."

Both will soon discover the limits of their power to undo Trump's economic blunders and steer an economy driven largely by forces outside their control.

Gas prices run through the strait of Hormuz

Gas prices were the single most powerful motivation for voters' rebellion against Republicans enabling Trump's policy choices. Reining them in requires reaching an understanding with Iran that reopens the strait of Hormuz. Schumer thinks Democrats can achieve that. "We are going to end the war," he said.

Trump may disagree. Congress is legally entitled to end wars — it's the only branch entitled to start one — but Republicans controlled Congress when Trump went to war, and he pursued it without asking their approval. Democrats could try to cut war funding, but they lack the 60 Senate votes needed to break a filibuster.

The trade war shows the same pattern. When the Supreme Court struck down Trump's "national security" tariffs for exceeding presidential authority, the administration reimposed many of them under a different statute, deploying a new, also spurious rationale. There's equally little Democrats can do about Trump's war on immigration: it is fully funded and can carry on unimpeded, further disrupting construction and other immigrant-reliant industries.

Even the easy wins are expensive

Reinstating ACA health insurance subsidies, or undoing cuts to Medicaid and food stamps in Trump's One Big Beautiful Bill Act, sounds like low-hanging fruit. But it hangs rather high: the budget deficit is already running at a whopping 6% of GDP.

Just preventing further damage will be an uphill battle. A lame duck Trump who no longer needs to please voters is likely to give free rein to his most destructive urges. Democrats can block his new legislative proposals, but they lack the votes to override presidential vetoes.

Optimists may argue that after Tuesday's shellacking, enough surviving Republicans could buck their president. But most who survived the bloodbath come from the most faithful MAGA districts and states — the least likely to abandon their leader.

An AI bubble underpins the whole economy

The economy itself — driven almost exclusively by a frenzied artificial intelligence investment boom — is unlikely to help Democrats ease voters' strains. Wall Street already doubts that massive spending on data-processing centers for training powerful AI models will pay off in time. The tech-heavy Nasdaq has fallen by more than 10% in the last month.

The debt math is striking. Goldman Sachs estimates the large AI hyperscalers have raised almost $200bn in bond markets so far this year — nearly twice as much as in all of 2025. Altogether, the bank added, AI-related firms have raised nearly $500bn in debt so far in 2026.

If that bubble pops and funding stops, Porter warns, it would likely deliver a downturn to beat even the Great Recession sparked by the 2008 housing bubble. A government hamstrung by $40tn in debt and interest rates near 20-year highs would have little fiscal space to soften the blow.

The mood, not the numbers

Here's the puzzle for practitioners tracking consumer sentiment: University of Michigan economist Justin Wolfers, who runs Platypus Economics, observes that neither unemployment nor inflation is bad enough to justify Americans' extreme economic pessimism. What's driving the sour mood, he argues, is a collapse in confidence in economic leadership.

Tuesday's Republican bloodbath might, on its own, improve Americans' spirits. Limited though their powers may be, Democrats will at least offer some resistance to Trump's most destructive impulses.

The forward risk is blunt. The economy will likely pose a greater challenge for the new Democratic Congress than it did for the Republicans now leaving power. In two years, Democrats might face voter anger over an economic scenario that has gotten palpably worse — and come to embrace the limits of their power, hoping voters blame the president rather than Congress for their economic unhappiness.
