Things got zesty from the get-go between tech entrepreneur Ron Davis and former City Council staffer Maritza Rivera in a live candidate event at KUOW, as the pair clashed over issues ranging from homelessness to tree canopy. Davis and Rivera are squaring off over District 4, which includes Wedgewood, Ravenna, the University District, and other neighborhoods. The seat is currently held by Alex Pedersen, who is not running for re-election.
