The State Committee, Executive Committee, County Committees, and Affiliates are explicitly prohibited from supporting a Democratic candidate who has opposition during a primary or Democratic opposition during a special election, nor shall any Party member use his/her office to support an opposed primary candidate or a candidate who has Democratic opposition in a special election. No Party member shall publicly support another candidate other than the Democratic nominee in a General Election; provided, however, nothing herein shall prevent any Party member from making any endorsement in a non-partisan election.
-Article I, section 7, Bylaws of the Democratic Party of Georgia

I have no dog in this fight.
I don't live in Georgia's 39th state Senate district, but I am a member of the state Democratic committee. And I was always taught that when Democrats oppose Democrats in the Democratic primary, the Democratic Party stays on the sidelines until there's a nominee.
But what do I know? After all, I've only been on the state Democratic committee for five years.
