The Sacramento City Council will have several fresh faces by the end of the year - but WHICH fresh faces, we don't know yet.  One incumbent, Lauren Hammond, is stepping down by choice.  Two more, Ray Trethaway and Robbie Waters, lost in the June primary.  Voters have already picked Trethaway's successor, but the other two seats are up for grabs on Tuesday.  So we invited the Sacramento Bee's city hall reporter Ryan Lillis in to break down those two races and discuss what the next council might look like.
