Final Candidate Truth Analysis

A leader should speak the truth. Different people may define truth differently. However, some statements can be factually verified[1].

Here is a final summary of verified statements[2] made by the Barak Obama-Joe Biden and John McCain-Sarah Palin tickets during the full presidential campaign:

Both candidate tickets tell the truth much less often and spread falsehoods much more often than they should, but Obama-Biden have told the truth more often than McCain-Palin[3]. Obama-Biden typical statements[4] range from True to Barely True[5]; McCain-Palin typical statements range from Mostly True to False[6]. Obama-Biden statements have been True 47% more often than McCain-Palin statements[7]. McCain-Palin have told 9 Lies[8], Obama-Biden have told 2 Lies. The full data is shown in the attached graph.

Both candidate tickets have been attacked[9]. However, Obama-Biden have been attacked with less truthfulness than has McCain-Palin[10]. Anonymous sources, primarily chain emails, made the least truthful attacks, and the Right attacked with less truthfulness than did the Left, shown in the attached figure[11].

The truthfulness of a leader is vital. A leader be can untruthful because of lying, which is a character or ethical issue. Another reason is ignorance, a competence issue. Whatever the case, Obama-Biden are more factually accurate than McCain-Palin to this point. Furthermore, the attacks on Obama-Biden have been less fair than those undergone by McCain-Palin. In short, Obama-Biden are more truthful than McCain-Palin, and McCain-Palin and his supporters have been less truthful about Obama-Biden.
