Campaign donation reports require this info everywhere- even for small town elections. I did paperwork for local Supervisor race. BTW- these reports are PUBLIC papers, and sometimes it is really interesting reading just who is contributing to your opposition candidates. We did, and it was VVEERRRY interesting. Vocally, local movers & shakers said one thing, but the donation and expenditures reports told a different story.
Made another contribution.
