Local & County
Oconee County consists of the unincorporated county areas and the four townships of Bishop, Bogart, North High Shoals, and Watkinsville. The county board of elections maintains a bunch of useful links, including rules about voter ID, absentee and early ballots, the official precinct maps (the one to the left from May 2017), etc.
Each of townships has its own elections board also, for local election issues. For the smaller towns, that’s just city hall, not a special board.
In the state house, we’re split between district 117 and district 119. Most of Oconee is 119, but 117 has the northeast edge of Oconee County, plus a bit of Clarke and a bit of Barrow Counties. 117 is represented by Rep. Deborah Gonzalez (D),. The rest of Oconee is district 119, which has most of Oconee plus a little bit of Clarke. 119 is represented by Rep. Jonathan Wallace (D). Both Deborah and Jonathan are newly elected in 2017, so their “official” phone numbers haven’t posted yet, but email and mailing addresses are at the links above.
In the U.S. Senate, all of Georgia is represented by two senators. Currently, they are Sen. Johnny Isakson (R), (770) 661-0999 and (202) 224-3643, and Sen. David Perdue (R), (404) 865-0087 and (202) 224-3521.
Yes, for the executive branch, it’s President Trump. But citizens are supposed to work the Federal government through their legislative representatives, even if he hadn’t closed most ways of contacting his office. (If you must, try a paper letter? Or Twitter?)
