David R. Jefferson, PhD Biography

Chair of the California Secretary of State's Voting Systems Technical Assessment and Advisory Board
Not Clearly Pro or Con to the question "Do Electronic Voting Machines Improve the Voting Process?"

“I do not want to be identified either as pro- or con on the issue of voting machines. I don’t mind being quoted, but the issue is too complex to summarize my position with one bit. More to the point, since I play a role sometimes in the certification of voting systems, it is inappropriate for me to be listed as being against them.” (Dr. Jefferson in a May 26, 2006 email to

“I do not argue that DREs are in principle a bad idea; indeed they have some real advantages to ordinary voters, to the disabled, and to voters who read a language other than English. But as currently designed, paperless DREs have fatal security and privacy flaws so dangerous that they could allow people with access to the software to modify election results on a national level and without detection.”
