BUFFALO, N.Y. — India Walton is the only candidate on the ballot after her victory in the Democratic primary, but she is still facing a vigorous write-in challenge from incumbent Mayor Byron Brown.

Walton shocked the four-term mayor in the June Democratic primary. But Brown has refused to quit. Some polls have shown him favored in the general election, but it isn’t clear whether enough supporters will write his name in on their ballots.

Walton would be Buffalo’s first female mayor and the first to identify as a democratic socialist. Brown would become the first person to win a major race as a write-in candidate in the state, and — if he gets a fifth term — Buffalo’s longest-serving mayor.

Results in the race might not be known right away. Tabulation of write-in votes won’t start until several days after the election.

Here are the three different scenarios: 

• Votes for Democrat India Walton, the only candidate on the ballot
• Ballots cast with the bubble filled in for a write-in vote
• And so-called "undervotes," in which someone potentially writes in a candidate without filling the bubble
