A campaign or outside group can set up many Facebook pages, each corresponding to a specific race or target demographics, and then put those pages’ messages in front of voters with ads. While these groups can sometimes hide behind a vague or misleading identity, Facebook has taken steps to address some egregious cases. As ProPublica reported in May, ads under the anodyne name “Ohio Primary Info” were shown to voting-age Ohioans. The advertiser, however, was not a source of objective information about the election. In fact, the ads were paid for by the campaign of Richard Cordray, now the Democratic nominee for governor.
