This is what happens when a Sonoma County Alliance candidate is challenged. The big money comes out to defeat the challenger.. In this case you have the expenditures by "Friends of John Sawyer for Council 2018." They are paying for mailers. It should be noted that the Sonoma County Democratic Party endorsed Lee Pierce. Yet this mailer was sent out, a "Democratic Voter Guide" which says to vote for John Sawyer. It also says to vote for Republican-backed Marshal Tuck.
Note how this mailer was sent to Lee Pierce himself. They were not smart enough to delete his name from the address list.
