Make sure you vote for Dems next year, even though your vote won’t make a difference in SF. Wait, was there any GOP candidate in SF at all? I guess your only choice is Dem anyway
The valid question is which end of Democrats you should vote for in SF. Ultra left, left, or moderate?
The only chance you could vote for a Republican candidate in SF is presidential election. Even in that case, your vote for Hillary or Donald has 0 impact
