Query: Election Forensics and the 2004 Venezuelan Presidential Recall
  Referendum as a Case Study   A referendum to recall President Hugo Ch\'{a}vez was held in Venezuela in
August of 2004. In the referendum, voters were to vote YES if they wished to
recall the President and NO if they wanted him to continue in office. The
official results were 59% NO and 41% YES. Even though the election was
monitored by various international groups including the Organization of
American States and the Carter Center (both of which declared that the
referendum had been conducted in a free and transparent manner), the outcome of
the election was questioned by other groups both inside and outside of
Venezuela. The collection of manuscripts that comprise this issue of
Statistical Science discusses the general topic of election forensics but also
focuses on different statistical approaches to explore, post-election, whether
irregularities in the voting, vote transmission or vote counting processes
could be detected in the 2004 presidential recall referendum. In this
introduction to the Venezuela issue, we discuss the more recent literature on
post-election auditing, describe the institutional context for the 2004
Venezuelan referendum, and briefly introduce each of the five contributions.
