A paper trail of each vote is crucial in all future federal elections. Although some states have tried to improve their methods, Congress must set the standards, based on serious research and experience, to guarantee accuracy while maintaining the speed and convenience of electronic machines.  Representative Rush Holt has introduced a bill, HR 2894, which bans all paperless voting, requires random audits, and provides funds to states to help facilitate improvements. Voters would complete paper ballots, which would be read by best available optical-scan voting machines, with original votes always available for recounts.
