This article presents a broad range of voting-related problems. Technology today plays a greater role in elections than at any other point in the history of democracy.

However, the fully electronic voting systems have raised considerable controversy because of a variety of factors, such as the proprietary nature of the software, the weakness of the certification criteria, the inability of black-box testing to provide full assurances of correctness, the general secrecy of the evaluation process, the vendor-commissioned evaluations, and the lack of any mechanism whereby independent recounting of the ballots and auditing of the vote totals can be performed
