You’ve seen him for years on daytime TV, the guy with the scrub-blue background and the high-energy advice about "miracle" supplements. But these days, Mehmet Oz—known to basically everyone as Dr. Oz—is more likely to be seen in a suit walking the halls of Washington than in a lab coat on a soundstage.
Is Dr. Oz a Republican? The answer is a definitive yes.
Not only is he a registered Republican, but as of early 2026, he’s one of the most powerful officials in the federal government. He currently serves as the Administrator of the Centers for Medicare & Medicaid Services (CMS) under President Donald Trump.
It's a wild shift.
One minute he's talking about green coffee bean extract with Oprah, and the next, he's overseeing a budget that’s basically a quarter of the entire U.S. national spend. Honestly, if you haven’t kept up with the news since his TV show ended in 2022, his political transformation might feel like it happened overnight.
The 2022 Pivot: From Celebrity Doctor to GOP Candidate
For a long time, people weren't really sure where Oz stood. Back in 2007, he used to describe himself as a "moderate Republican." He’d name-drop people like Arnold Schwarzenegger or Teddy Roosevelt as his political North Stars.

Then came the 2022 U.S. Senate race in Pennsylvania.
That was the turning point. Oz didn't just run as a Republican; he ran as a MAGA-aligned Republican. He had to fight through a brutal primary where critics called him a "carpetbagger" (because he’d lived in New Jersey for years) and a "RINO" (Republican In Name Only).
To prove his conservative bona fides, he leaned hard into some key positions:
- The Second Amendment: He started appearing at gun ranges, talking about his rights as a gun owner.
- Abortion: He shifted from a more "pro-choice" leaning past to a firm "pro-life" stance, saying he was "relieved" when Roe v. Wade was overturned.
- Energy: He became a massive cheerleader for fracking and Pennsylvania energy independence.
He barely won that primary. I mean, it was incredibly close—he beat Dave McCormick by less than 1,000 votes. He eventually lost the general election to John Fetterman in a race that was, frankly, one of the weirdest and most expensive in history. (Remember the "crudité" video? Yeah, that was this race.)
Is Dr. Oz a Republican in the Trump Administration?
Even though he lost the Senate race, Oz didn't disappear. In late 2024, after Donald Trump won his second term, he tapped Oz for the CMS role. The Senate confirmed him in April 2025, mostly along party lines ($53-45$).
Now, he’s a key architect of what the administration calls the "MAHA" movement—Make America Healthy Again.
He's not just a "member" of the party anymore; he's a leader in it. He spends his weekends at the White House working on plans to replace or overhaul the Affordable Care Act (ACA). He’s also been working closely with Robert F. Kennedy Jr. to tackle what they call the "illness industrial complex."
It’s a strange alliance for some to wrap their heads around. You have a world-renowned heart surgeon and a former Democrat (RFK Jr.) leading a Republican charge against the current healthcare system.
Where He Stands on the Issues Now
If you’re trying to pin down exactly what kind of Republican he is, look at his 2026 policy pushes. He isn't exactly a "small government" guy in the traditional sense because he's running a massive government agency.
Instead, he’s focused on:
- Cutting Waste: He’s constantly talking about "fraud and abuse" in Medicare.
- Dietary Guidelines: He recently co-authored an op-ed with Ben Carson about "reclaiming the food pyramid" and pushing for whole, nutrient-dense foods.
- Choice and Competition: At recent industry summits like JPM26, he’s been pitching "choice" as the solution to rising premiums, wanting private Medicare Advantage plans to compete more aggressively.
Why People Still Get This Wrong
The reason people still ask "Is Dr. Oz a Republican?" is usually because of his 13 seasons on The Dr. Oz Show. On TV, he was a populist. He stayed away from partisan bickering because he wanted to sell books and get ratings from everyone—blue states, red states, didn't matter.
Plus, his early medical career was spent in the very "elite" circles that many modern Republicans distrust. He was a professor at Columbia University and a surgeon at New York-Presbyterian.

But that version of Oz is effectively gone.
He has fully embraced the GOP’s shift toward populism. He’s traded his scrubs for the political arena, and he seems to be staying there for the long haul.
Actionable Insights for the Informed Voter
If you’re following Oz’s career because you’re concerned about your healthcare or just want to stay politically savvy, here’s what you should keep an eye on:
- Watch the ACA Tax Credits: Oz is currently in the middle of a massive debate over whether to extend the tax credits that keep insurance affordable for millions. If these expire in 2026, premiums could skyrocket.
- Monitor "MAHA" Policy: If you're into health and wellness, pay attention to the new USDA/HHS dietary guidelines coming out. Oz is a primary voice in how the government will define "healthy" for the next five years.
- Follow the Budget: Since Oz oversees a huge chunk of the national budget, his decisions on Medicare payments will directly affect how much your doctor gets paid—and how much you pay out of pocket.
Dr. Oz isn't just a Republican on paper; he's a central figure in the party's 2026 agenda. Whether you love him or hate him, his transition from the "Oprah doctor" to a high-ranking government official is complete.
To stay updated on his specific policy changes, you can track the official CMS newsroom updates or follow the upcoming 2026 Congressional hearings where he is expected to testify on healthcare reform.
