How well do voters (i.e., an electorate) know and thus are able to assess people running for public office? As the proportion of people who know a candidate firsthand decreases, the importance of the campaign ads and debates increases. In other words, the candidate's marketing plays a greater role in who wins. At an empire-level, such as the U.S. Government, an overwhelming percentage of people in an electorate (e.g., voting in a U.S. Senate race, or that of the federal president) are significantly influenced by the candidates' respective media campaigns for lack of real knowledge. In a U.S. presidential campaign, financial contributions are vital in being able to orchestrate an empire-wide media campaign. Also, how a campaign manipulates the media coverage of the candidate is very important. The case of Sarah Palin, who ran as John McCain's running mate in 2008, illustrates the extent of distance that can separate what the public "knows" of the real person from the media-made candidate. When people learned of her shocking ignorance of government, the distance was suddenly transparent, and yet no electioneering reforms were subsequently put into effect. Americans still had to rely on presidential debates to get a glimpse of the "man behind the curtain."
