Susan Adams Marin County Supervisor,ABAG Vice President voted out of office when the people of her district discovered that she recommended her community for a Priority Development Area and then denied it. He duplicity to the voters was repaid with recall campaign and landslide loss in 2014.
Steve Kinsey, Marin County Supervisor, MTC President resigned in 2016 while the subject of massive breach of ethics for 200+ meetings with developers while also serving on the California Coastal Commission.

Jake MacKenzie, Rohnert Park Councilman current MTC chairman , de throned on 1/22/2019 after his fellow councilpersons discovered that he had failed to report about the CASA Compact which may cost his community $15 million dollars in housing funds. He then did not report back the concerns of his community to ABAG where he also serves on the CASA Committee.
