A RINO is a “Republican in Name Only.” Republicans use the term for a fellow Republican they think isn’t conservative enough, or loyal enough to the party or its leader, to deserve the name. It’s an insult, not a formal status. It has no legal meaning, it doesn’t change anyone’s voter registration, and no party committee hands it out. If you were actually looking for the animal, the cold virus or a nosebleed device, the quick table below has those.
What is a RINO?
- What it stands for: Republican In Name Only.
- Who uses it: Mostly Republicans, about other Republicans. Democrats rarely use it, because the point is to say someone isn’t a real member of the speaker’s own team.
- What it signals: The speaker believes the target has broken with the party on a core issue, or with the party’s leader. Since 2016, that leader has been Donald Trump.
- What it isn’t: An official designation. A person registered as a Republican stays a Republican no matter how many people call them a RINO.

What “RINO” means in politics
The label is subjective, and it often tells you more about the person using it than about the target. A fiscal hawk calls a colleague a RINO for voting for a spending deal. A social conservative uses it on someone who supports abortion exceptions. In today’s GOP, it’s most often about one thing: whether a Republican backs Donald Trump.
What usually triggers the RINO label
- Spending and debt: Voting for large spending bills, debt-ceiling deals or stopgap funding bills that pass with Democratic votes.
- Taxes: Supporting any tax increase, especially after signing an anti-tax pledge.
- Immigration: Backing a path to legal status, as some Republican senators did with the 2013 “Gang of Eight” bill.
- Guns: Votes like the 2022 Bipartisan Safer Communities Act, which 15 Senate Republicans supported.
- Abortion: Taking positions short of what activists in a given state demand.
- Trump: Voting to impeach or convict him, voting to certify the 2020 results, criticizing him publicly, or endorsing his primary rivals.
What a RINO is not
It’s not a formal status. A party can censure a member, but that’s symbolic. In November 2021 the Wyoming GOP voted to stop recognizing Rep. Liz Cheney as a Republican. She stayed a registered Republican and kept running in the party’s primary.
It’s not the same as “moderate.” Plenty of solidly conservative lawmakers have been called RINOs over a single vote. Cheney voted with Trump’s position more than 90% of the time during his first term, according to FiveThirtyEight’s tracker, and still became one of the best-known targets of the label.
Where the term RINO came from
The phrase “Republican in name only” is older than the acronym. Origin stories conflict, so here is what’s actually documented next to what’s only repeated online.
| Claim | What’s cited | How reliable |
|---|---|---|
| Theodore Roosevelt coined it | Repeated online. No primary source has turned up. | Weak; treat it as a myth. Roosevelt’s 1912 break with party regulars probably explains why the story sticks. |
| 1992 New Hampshire newspaper | An early print use in Manchester’s Union Leader, cited by etymology researchers | Strong as an early documented print use |
| 1993 California activist | Celeste Greig of the California Republican Assembly, whose RINO buttons targeted Los Angeles mayoral candidate Richard Riordan | Credible as a popularizer, though not necessarily the inventor |
| 1840s “rino” | Dictionary.com notes a much older use of the word | Real, but unrelated to politics |
The term spread in three waves. In the 1990s it moved through talk radio and activist newsletters. During the 2010–2014 Tea Party era it became a primary-season weapon: Utah Sen. Bob Bennett lost at his state convention in 2010, Indiana Sen. Richard Lugar lost his 2012 primary, and House Majority Leader Eric Cantor lost his 2014 primary after attacks on his immigration record. In the Trump era, the president himself started using it, often on social media, and it became the party’s default insult.
How the RINO label is used today
In primaries and endorsements
RINO is a primary-season word. In a general election, the voters you need to persuade don’t care whether a Republican is “real.” In a primary, that question is often the whole campaign. A typical pattern looks like this: the incumbent casts a controversial vote, a challenger appears, a national figure endorses the challenger, and “RINO” shows up in mailers, ads and on social media.
Trump-era examples
- Liz Cheney: She voted to impeach Trump in January 2021 and served as vice chair of the January 6 committee. Trump repeatedly called her a RINO. She lost the 2022 Wyoming primary to Trump-endorsed Harriet Hageman by about 37 points.
- The 10 House impeachment votes: Of the ten House Republicans who voted to impeach in 2021, four retired and four lost primaries. Only Dan Newhouse and David Valadao won reelection in 2022.
- Mitt Romney: Trump called him a RINO more than once. Romney voted to convict in both impeachment trials and didn’t seek reelection in 2024.
- Brian Kemp: Trump attacked the Georgia governor after the 2020 election. Kemp still beat Trump-backed David Perdue in the 2022 primary by more than 50 points, which shows the label doesn’t always stick.

Common questions: who decides who is a RINO?
Who decides?
Nobody official. It’s decided by whoever has the biggest megaphone in a given race. Today that’s usually Trump’s endorsement, then state party leaders, activist groups and influential media figures. Voters settle it in the primary.
Is a moderate Republican automatically a RINO?
No. Many moderate Republicans, especially in swing districts, are never called RINOs because they stay loyal on the issues their base cares about most. And as Cheney’s case shows, a solidly conservative record doesn’t protect you if you break with the party’s leader.
How do you know if you’re a RINO?
There’s no test. Practically speaking, the label follows breaks with the party’s leader more than overall ideology. If your views match the GOP platform on most issues, you’re a Republican by any formal measure, whatever someone says online.

Florida relevance: why RINO fights matter in a closed-primary state
Florida holds closed primaries: only voters registered with a party can vote in that party’s primary. Because Republicans now outnumber Democrats in Florida registration by more than a million voters, and many districts are safely red, the GOP primary is often the real election. That’s exactly where the RINO label does its work.
Three details Florida voters should know:
- The registration deadline is 29 days before the election. If you want to vote in the Republican primary, you have to change your party affiliation before that deadline. Changes made after it don’t count for that primary.
- The universal primary rule. If every candidate in a race belongs to the same party and nobody will face them in the general election, all voters can vote in that primary. A single write-in candidate closes the primary again, a loophole both parties have used.
- Check the record, not the mailer. RINO accusations are common in legislative and county-level GOP primaries. Before you believe one, look up the candidate’s actual votes on the Florida Senate or Florida House website.
The bottom line: “RINO” is a judgment about loyalty, not a fact about party membership. When you see it, ask who’s saying it, which vote set it off, and whether the target’s record supports the claim.
