You’re standing in the voting booth. The curtain is closed—or you're leaning over your kitchen counter with a mail-in envelope—and you hit a name you don’t recognize. Or maybe it’s a judicial retention election where you have zero opinion on whether Judge Smith keeps their seat. You start to wonder: can you leave parts of a ballot blank, or will the whole thing get tossed in the trash by some unforgiving machine?
It’s a common fear. People worry that an "incomplete" ballot is a "spoiled" ballot.
Here is the short, definitive answer: Yes. You can absolutely leave parts of your ballot blank. In the world of elections, this has a formal name. It’s called "undervoting." And honestly? It happens way more often than you’d think. According to various state election data, thousands of voters every cycle choose to skip specific races while still weighing in on the "big" ones like President or Governor.
The Myth of the "All or Nothing" Ballot
There’s this persistent urban legend that if you don’t fill out every single bubble, the tabulator will reject your entire sheet. That is simply not true. Voting isn't a standardized test where you're graded on completion. It’s an exercise of your individual will. If you only want to vote for the person running for Sheriff and leave everything else empty, that’s your right.
When your ballot goes through the scanner, the machine looks at each race independently. If it sees a mark for President, it counts it. If it sees nothing for the "Water Conservation District Sub-Director," it just moves on. It doesn’t get "confused." It just records a "no vote" for that specific contest.

The only time a machine usually spits a ballot back at you is if you "overvote." That’s when you fill in two bubbles for a race where you’re only supposed to pick one. In that case, the machine usually gives you a chance to fix it because it can't guess who you actually wanted. But for blanks? The machine is perfectly happy to let them slide.
Why People Choose to Undervote
Sometimes it’s a lack of information. You might be a deeply informed voter when it comes to national policy but have no clue who the candidates for Soil and Water Supervisor are. Rather than guessing—which some people feel is irresponsible—they just skip it.
Other times, it's a protest.
If there’s only one person on the ballot for a specific office and you don’t like them, leaving it blank is a way of saying "none of the above." While it won't stop them from winning if they're unopposed, it does show up in the final certified results as an undervote. Election nerds and political consultants actually study these numbers. If a candidate wins but has a massive number of undervotes, it tells the party that their candidate isn't particularly popular, even if they technically won.

The Legal Side: Straight-Ticket Voting and Beyond
Historically, some states had "straight-ticket" options where you could pull one lever or fill one bubble to vote for every candidate in a specific party. Most states have moved away from this. For example, Texas famously abolished straight-ticket voting recently, forcing voters to go through every single race.
This change led to a lot of anxiety. People started asking, can you leave parts of a ballot blank if you get tired halfway through the three-page ballot? Yes. Even in states that used to have "one-click" voting, you are never legally required to vote in every contest.
However, you should be aware of how this impacts "down-ballot" races. These are the local positions—school board, city council, local judges—that actually affect your daily life more than the White House does. When you skip these, you're essentially letting a smaller and smaller group of people decide who runs your local schools or sets your property taxes.
What About Write-Ins?
Some people think that if they don't like the candidates, they must write in a name instead of leaving it blank. You can do that, but be warned: in many states, write-in votes only count if the person has formally registered as a "certified write-in candidate." If you write in "Mickey Mouse" or your neighbor's name, it’s effectively the same as leaving it blank in terms of the outcome, though it might give the poll workers a mild chuckle during the manual audit.

How to Handle a Ballot You Aren't Ready For
If you’re worried about leaving too many blanks, the best strategy is prep work. Most counties post a "Sample Ballot" online weeks before the election.
- Go to your Secretary of State’s website.
- Search for your specific precinct's sample ballot.
- Print it out.
- Research the names you don't know at home.
In many states, you can actually bring that piece of paper or even your phone (check local laws on phone use in booths!) into the voting area with you to use as a cheat sheet. This takes the pressure off. You won't feel that "test anxiety" of staring at a blank bubble and wondering if you're "doing it wrong."
Practical Steps for Your Next Election
If you find yourself in the booth and realize you're just not comfortable voting on a specific bond measure or a local race, don't panic.
- Focus on what you know. Your votes for the offices you did select will be counted exactly the same as if you had filled out the entire sheet.
- Don't overthink the machine. The tabulator is designed to handle partial ballots. It will not "void" your vote for President because you skipped the local tax assessor race.
- Double-check your marks. Make sure that the races you do care about are filled in clearly. If you make a mistake, don't try to cross it out. Ask a poll worker for a new ballot. This is called "spoiling" your ballot, and you're allowed to do it (usually up to three times) to ensure your intent is clear.
- Verify the "back of the ballot." A lot of people accidentally "leave parts of the ballot blank" because they forget to flip the paper over. Always check the back for ballot initiatives, constitutional amendments, or non-partisan races.
Ultimately, your ballot belongs to you. Whether you fill in every circle or just one, your voice is recorded for the choices you make. Just ensure that the parts you do fill out are the ones that matter most to you, and don't let the "completionist" urge force you into voting for someone you don't actually support.
Before you head to the polls, verify your registration status and your local polling place through official government portals like Vote411 or Ballotpedia to see exactly what your specific ballot will look like this year.
