Sen. Ted Cruz, R-Texas, believes that fear of a rising wave of progressives is paralyzing possible bipartisan work on permitting reform that would otherwise create fertile ground for collaboration.

"That dynamic is dangerous right now because they are terrified of the extreme left. Finding a middle ground on ideological issues right now is … the prospects for success, particularly between now and election day, are not high," Cruz said at an energy summit hosted by Club for Growth and Arnold Ventures on Thursday.

"Schumer is truly terrified right now," he added, referring to Senate Minority Leader Chuck Schumer, D-N.Y.

Cruz’s political assessment underscores what progressive momentum in the 2026 midterms means for more establishment figures in the Democratic Party — and especially the ones already in Congress — and the policy areas that legislators may still want to address before the November midterm elections.

"They’re in the middle of a revolution," Cruz said. "Their problem is that they’re very driven by their interest groups. They’re captured by their activists."

His remarks came as he delivered an address at an energy affordability summit hosted by the Club for Growth, a free-market group that advocates for limited government. In particular, the event centered on permitting reform, an area where Democrats and Republicans have found some overlap.

Although differences remain about just how far to scale back regulations or how far to push legislative changes, lawmakers at the event stressed that bipartisan work on cutting back red tape could meaningfully expand American access to energy projects domestically.

Energy Secretary Chris Wright noted how regulatory bodies had prevented the expansion of nuclear energy — a source of power that is uniting Republicans and Democrats as a new frontier in a space apart from fossil fuels.

"We have built three new nuclear reactors in like the last 40 years. It went quickly from: we didn’t even know about the technology, to 20% of U.S. electric generation from nuclear reactors," Wright said.

"We created the Nuclear Regulatory Commission… in the name of safety, no malintent. But since that creation, we’ve built almost no reactors in the United States since. If it’s so uncertain and so long to permit something, it’s just not worth investing in. That’s awful! Nuclear is just an awesome energy technology."

Sen. Bernie Moreno, R-Ohio., stressed that many of the discussions around reform have come down to a matter of practical details.

"There's a lot of conversations going on not about who's going to fight with whom or who is going to take credit for it, but rather what is the mechanics of getting it done," Moreno said at the Club for Growth event.

"When it comes to permitting reform, if we can actually pull this off, Scott, what does it mean? It means lower energy prices for all Americans, us taking better care of our environment, being good stewards for the next generation. Those are worthy goals that should unite all of us, and I'm hopeful that we can get that done," Moreno said, speaking to conservative political commentator Scott Jennings, a moderator at the event.

Despite a sense of optimism among several speakers — and even from Cruz himself — Cruz warned listeners that progressives already have a very real presence inside the Capitol that casts a shadow on permitting reform and other areas.

"It is not the case that every Senate Democrat is a Marxist or Islamist. What is the case is that every Senate Democrat is terrified of the Marxists and Islamists. Because that’s where the energy is in their party, that’s where the power is, that’s where the money is; it's where the young people are. I think Mamdani is the single most powerful Democrat in the country," Cruz said, referring to the socialist mayor of New York City, Zohran Mamdani.

Since Mamdani, a self-proclaimed socialist, came to power earlier this year, a series of progressive candidates backed by the Democratic Socialists of America (DSA) have won key primary races and even toppled veteran incumbents.

A few notable races include New York's socialist Darializa Avila Chevalier and her victory over incumbent Rep. Adriano Espaillat, D-N.Y., the veteran chair of the Congressional Hispanic Caucus. Along those lines, Melat Kiros, another socialist in Colorado, unseated 30-year incumbent Rep. Diana DeGette, D-Colo.

With pressures like that, Cruz argued that it’s difficult to find legislators who are willing to separate themselves from progressives.

He believes there isn’t leadership to push back against that progressive momentum.

"Look, Schumer is known for a lot of things but acts of principle and courage are not among them," Cruz said.
