From taxes to the environment to public broadcasting like PBS and NPR, the Senate has recently passed record levels of legislation and confirmed record numbers of nominations with senators representing less than half the people.
Using historical data, GovTrack found 56 examples of Senate votes on legislation that passed with senators representing a “population minority.” 26 of those 56 examples, nearly half, have occurred since President Donald Trump’s current term began.
Several of the second Trump administration’s most prominent members were confirmed by Senate “population minority” votes – including RFK Jr. (Secretary of Health and Human Services), Pete Hegseth, Pam Bondi, Kash Patel, and Tulsi Gabbard.
The oldest example GovTrack found of a “population minority” Senate vote is actually famous: Clarence Thomas’s 1991 Supreme Court nomination by President George H. W. Bush. The Senate approved Thomas with 52% support, but 49% of the population.
He still serves on the Court today.
GovTrack found three other “population minority” Senate confirmations for Supreme Court justices, totalling four: Thomas plus Trump’s three first-term nominees. All four still serve on the Court.
Currently, Republicans hold a Senate majority: 53 to 47. However, based on the Census Bureau’s current estimates, it’s actually the other way around by population: Democratic senators represent a 53% majority of the states’ population, versus Republicans with 47%.
How is this possible? Because while the U.S. House is apportioned based on population, with larger states receiving more representatives, the U.S. Senate guarantees each state two senators regardless of size.
This was baked into the American system from the beginning, creating what political scientists call a “counter-majoritarian” institution.
In 2025, according to Census Bureau estimates, the most populous state (California) had about 67x the population as the least populous: Wyoming. Today, a Senate voting majority could be cobbled together from senators representing just 17% of the population.
But that’s actually been the same for a while. Going back to 1900, a Senate voting majority could be cobbled together with senators representing 16% to 20% of the population.
Instead, small states may be more politically aligned than they used to be and are voting together more often as a bloc.
Senators have recently taken advantage of old rules, and also changed some rules, to use lower vote thresholds. This means votes are more often succeeding with less support.
Both parties contributed to this.
In 2013, under President Obama, Senate Democrats changed the threshold for most nominations from three-fifths to a simple majority. They left it at three-fifths for the Supreme Court, though.
Then in 2017 during Trump’s first term, Senate Republicans changed the threshold for the Supreme Court, too, to confirm Justice Gorsuch by a simple majority. (This rule applied to all subsequent justices, too.)
As for legislation, many of the recent “population minority” Senate votes used the Congressional Review Act of 1996, which lowered the usual Senate vote threshold from three-fifths to a simple majority for certain deregulation bills. The One Big Beautiful Act and the Rescissions Act were both voted on under other rules, which lower the vote threshold for certain spending-related bills.
So the three-fifths threshold is now gone for nominations and some types of legislation.
It might not stop there. Trump has called for the Senate to end the three-fifths threshold for all legislation, in order to enact certain Republican policies – particularly regarding election rules. If that happens, “population minority” Senate votes could become even more frequent.
Why does this usually benefit Republicans?
This discrepancy usually benefits the GOP, since they tend to represent smaller states.
This small-state Republican benefit also holds true at the presidential level. Indeed, two presidents in living memory won election despite losing the national popular vote, both Republicans: George W. Bush in 2000 and Donald Trump in 2016.
The Congressional Review Act, which makes it easier for Congress to deregulate – and the rules for rescissions bills, which makes it easier to cut funding – also are more aligned with Republican goals than Democratic goals.
But for better or for worse, it’s clear that the Senate is diverging from popular opinion far more than ever before, at least in recent memory. Even if one believes the Senate is, in fact, “right” while popular opinion is “wrong.”
