That's true with TV ads. You can't tell a huge whopper in a TV ad without lots of people seeing it and saying "WTF? I can't vote for this guy." You can, however, promulgate specific conspiracy theories in highly targeted ads that the majority of people never see. If 0.1% of people believe some crazy theory, you can show them ads linking the opposing candidate with it. Perhaps almost everyone believes some crazy theory. In the future, everyone will be fooled for 15 minutes.
