Black Box Voting: Ballot – Tampering in the 21st Century is a site by Bev Harris and others on the issue of electronic voting. It includes PDFs of Harris’ book Black Box Voting. The site blogs stories and news on the issue.
I had an earlier blog on this at grockwel: Research Notes: Why War? and Computer Voting Machines.
An article that gives some context on Harris is at, The Herald News: Activist: E-Voting to be a ‘Train Wreck’.
