Minutes into filling out my absentee ballot last week, I was momentarily distracted by my dog Seamus. A moment later, I realized in horror that I was filling in the wrong bubble — accidentally voting "no" on a ballot measure that I meant to vote "yes" on.

It was only a few ink marks, but it was noticeable enough. Trying to fix my mistake, I darkly and fully filled in the correct circle and then, as if testifying to an error on a check, put my initials next to the one I wanted.

Then I worried. As a reporter who has previously covered election security for years, I went on a mini-quest trying to understand how a small mistake can have larger repercussions.

As Los Angeles County's 5.6 million registered voters all receive ballots at home for the first time, I knew my experience could not be unique. But I wondered, would my vote count? Or would my entire ballot now be discarded?
