With vote-by-mail ballots in your possession, this is why you listen to the East Bay Insiders podcast. In Part 1 of our East Bay June Primary Preview, Shawn and I break down the big Alameda County District Attorney race, Alameda County Sheriff contest, and the campaign to replace Wilma Chan on the Alameda County Board of Supervisors in District 3. We also take a look at some of best and worst mailers of the primary season. Listen to Part 2 on Thursday (AD20, SD10, AD24, Education races)
