David Chiu was the first mayoral candidate to cast his ballot Tuesday morning. Independent candidate Joanna Rees cast her ballot shortly after. They both say they have done endless amounts of campaigning, in part just to let people know that an election is coming up. A recent poll found that many San Francisco residents do not know who the current mayor is or that the election is approaching.
Current Mayor Ed Lee was also planning on voting Tuesday morning.
Normally, more of the candidates would cast their ballots on Election Day but they say since more and more people are voting by mail it's more important to get their names out early.
The election is scheduled for Nov. 8.
