In a comment left on a post and confirmed by a direct email – Dry Creek Trustee Jeff Randall withdrew from the AD-04 Circus:

After a lot of soul searching, I have decided that I am not ready to put forth a credible campaign.  While I truly believe that I have a lot to offer the voters of the 4th assembly district, I do not have the organization, the money, and the time to run.  I will continue to serve the Dry Creek School district on the Board of Trustees, and my 140 7th graders at Arcade Middle School.  Perhaps down the road I will launch a campaign for the State Legislature- but I will need more time, and be better organized to do it right.
