If no one else enters the race, according to the California Election Code, the Council can then do one of three things: (1) Appoint to the office the person who has been nominated. (2) Appoint to the office an eligible elector if no one has been nominated. (3) Hold the election, if either no one or only one person has been nominated. (California Elections Code 10229.a.iii)
If no one else runs, and the current two declared candidates qualify, then the Council, if it so chooses, can appoint the two to the Council.
This means no race, no local town election.
If there is a local election and only and are on the ballot, it won't matter how many votes they receive because they will be running unopposed.
It also won't matter how or what they say at interviews, forums or debates because there probably won't be any ... why bother if there is no race?
Two seats + two candidates = two winners and no "losers" (except for the voters).
