The Electronic Frontier Foundation has teamed up with Verified Voting to try to get members of the U.S. House of Representatives to sign up as co-sponsors of HR 550, the Voter Confidence and Increased Accessibility Act of 2005, which was re-introduced in the House in February. This bill would require that electronic voting include a paper receipt and the capacity for manual recounts, ensure that disabled and those who don't speak English as their native tongue are capable of voting, and enhances security requirements for electronic voting systems. The latter requirements include disclosure and certification of source code, prohibition of the use of wireless connections, and a number of other provisions which appear to me to be reasonable requirements for security. The bill authorizes expenditure of $150M for fiscal year 2006 to enable states to meet these requirements.
Arizona Reps. Grijalva and Pastor have already signed on as co-sponsors. Hayworth, Flake, Kolbe, Renzi, Shadegg, and Franks have not.
