Note a huge reason to target political ads is precisely that you can send your targets highly offensive or obviously misleading ads that you know they won't be offended by, without showing the rest of the electoral how vile the shit you're slinging at voters really is. Targeting covers the stench. Keeping the average voter from seeing your nastiest ads is just as important as who does see the ads. Democracy is about informing voters, targeting is all about keeping information about your ads from most voters.
