This Common Cause Massachusetts about senate bill 327 factsheet begins, 'Recent history shows many examples of errors or malfunctions by voting equipment in Massachusetts. Post-election audits would allow election administrators to ensure that voting machines have accurately counted all ballots. The audit is conducted by comparing reported preliminary machine counts to manual counts of the same ballots in 3% of randomly selected precincts to ensure that they match and that machines are accurately recording the vote. Audit-ing is a low-cost program that could be primarily funded by funds authorized by the national Help America Vote Act.'
