Sen. Mike Lee (R-Utah) has a simple answer for anyone worried about billionaires flooding politics with cash: make government smaller.

On Saturday, Lee responded on X to a post from Sen. Bernie Sanders (I-Vt.), who had accused Elon Musk and other billionaires of trying to buy political influence ahead of the 2026 midterm elections.

"We have a constitutional republic, not a democracy (yes, it matters)," Lee wrote.

"If you want less money in politics, limit the power of government," he added.

That's the libertarian-leaning argument in a nutshell. Money chases power, so if Washington has less power over the economy and people's lives, there's less reason to spend fortunes trying to influence it. Whether you buy that or not, Lee is all in on it.

The First Amendment Angle

Lee also argued that restricting political speech would undermine First Amendment protections and, conveniently for his side of the aisle, benefit Democrats.

"Circumventing the First Amendment to limit political speech would further empower the Leftist Media Cartel™, helping Democrats," he wrote.

So in Lee's telling, campaign finance restrictions aren't just unconstitutional. They're a political gift to the other team.

Sanders Warns of Oligarchy

Sanders, meanwhile, isn't backing down. He wrote on X, "Elon Musk and his fellow billionaires think they can buy our democracy. They are wrong. Together, we will defeat oligarchy."

In his speech, Sanders accused billionaires of using their wealth to influence elections and cited Musk's political spending in support of Republicans, which has been reported at roughly $366 million for the 2026 election cycle.

"Billionaires can no longer be allowed to buy elections. We need to have one person, one vote. That's called democracy," Sanders said.

He also called for a wealth tax on billionaires and stronger safeguards for artificial intelligence.

So you've got two senators looking at the same pile of campaign cash and seeing completely different problems. One sees a speech issue. The other sees a democracy issue.

Democrats Keep the Pressure on Costs

The spending fight isn't happening in a vacuum. Earlier this month, former Vice President Kamala Harris criticized Trump over rising costs and the Iran war, saying Americans struggled to afford essentials.

She wrote, "People are tired of having to choose between gas and groceries," and urged voters to check what she called Trump's "callous, corrupt, and incompetent administration."

Last month, former House Speaker Nancy Pelosi accused Republicans of favoring wealthy Americans while working families faced rising costs.

She criticized tax breaks for the wealthy and taxpayer spending on Trump's Iran war, saying, "Republicans are making you pay more so the rich and powerful can cash in."

In May, Illinois Gov. JB Pritzker (D) accused Trump of opposing funding for Medicaid and SNAP while supporting White House projects.

He wrote, "Apparently, we can afford anything — as long as it's for Donald Trump."

Put it all together and the 2026 midterms are shaping up as a referendum on who gets what, and who pays for it. Lee says the answer is less government. Sanders says it's less billionaire money. Voters will get to sort that out soon enough.
