Following the February 5 presidential primary, several county clerks in New Jersey asked an independent researcher to study the vote results on the state's electronic voting machines. The vendor, Sequoia, has threatened legal action, but so far hasn't taken any. Initial results suggest that there were some inconsistencies in vote tallies, although none were enough to reverse the election results themselves.
Since last year, several states have requested audits of electronic voting systems. In California, the audits resulted in some systems being scrapped for the 2008 presidential primaries. As we turn our attention to the fall 2008 presidential election, several security researchers have come forth with their own studies and suggestions. One of them is Brian Chess, chief scientist at Fortify.
