Election forecaster Nate Silver predicts that the 2026 midterms could mark the beginning of a post-Trump political era, while also offering an early test of voters' attitudes toward artificial intelligence and the data centers that power it.
"If the election goes roughly as the polls say it will go, then in some ways, it would mark the end of the Trump era," Silver said on the Ezra Klein podcast Tuesday.
Silver argued that a poor Republican performance would immediately shift political attention toward the 2028 presidential race and turn Trump into a "super lame duck" during the final two years of his term.

"Maybe we're on the verge of something different," Silver said, citing generational turnover, Trump's approaching departure from office and the emergence of new political issues.
The forecaster pointed to a steady decline in President Donald Trump's approval ratings because of the war in Iran, economic worries and higher gas prices. He noted voter fatigue after more than a decade of Trump dominating national politics.
"He's been the dominant figure in American politics since whatever, mid-2015," Silver said. "That's a really long time."
Do Democrats Retake the House and Senate?
Silver gamed out a few scenarios—including one where the success predicted for Democrats fails to materialize.
He said he can see a scenario where Democrats lose several of the closest Senate races, including James Talarico's race in Texas and Troy Jackson's in Maine.
"Maybe pollsters and Democrats are getting their hopes up a little bit too high to think you could win in these R plus 12 states who have been R plus eight. Then yeah, but we just kind of reached the point where we ran out of like oxygen climbing up that big red hill, right?" he said.
Several races have "a lot of outsized narrative importance," including Talarico's, along with Abdul El-Sayed's Michigan battle, Silver added.
"You know, the possibility of Democrats being competitive in Texas, a sort of return of a religious left. Abdul El-Sayed is going to be seen as a very important test. He's actually not a DSA guy, but sort of a more left populist. ... It feels like there's going to be a lot of attention on how he specifically does."

Silver identified another key question: whether moderate Democrats outperform more progressive candidates. He repeatedly highlighted candidate quality as a major factor in competitive Senate races and suggested November's results could influence the party's internal debate heading into 2028.
"If El Sayed were to lose, then win or lose the Senate, that's a very bad narrative for progressives," he said.
At the same time, Silver cautioned against reading too much into any single race, noting that broader political conditions remain more important than ideology alone.
Klein asked Silver if it's possible that Trump doesn't really care whether the GOP holds the Senate, saying that he has made most of his policy changes through executive orders.
"If winning the midterm means giving Republicans space from him and, you know, backing people he doesn't really like, yeah, then no" Silver said.
AI Emerges as a Political Issue
Silver suggested the election could provide an early indication of the potential backlash against artificial intelligence, particularly against the construction of data centers that support AI systems.
"The two big sub-storylines of November 3 are one: how do progressives do relative to moderates?" Silver said. "But then, is there evidence of like an AI backlash from the state-by-state results?"
He suggested analysts could eventually examine whether Republican candidates underperformed in areas where major data center projects were proposed or under construction.
Silver also argued AI could become one of the defining issues of the next presidential election. "With AI looming too," he said, "it could be the biggest issue of 2028."
The election forecaster added that the midterms could be remembered not simply as a referendum on Trump, but as a transition point. He described a political environment shaped by economic uncertainty, foreign policy tensions and rapid technological change. If Democrats perform as current polling suggests, Silver believes the election could accelerate a shift away from the political era Trump has dominated for more than a decade and toward a new debate over who leads both parties, and how the country responds to AI-driven change.
"It's not quite clear to me how big an issue AI is in this election," Silver said. "I think maybe more than people assume."
