general collecting and counting these printed records can be difficult. Records printed on continuous rolls of paper is more difficult than counting standard paper ballots or even punch cards. Privacy concerns DRE VVPAT systems that print the ballot records out in the order in which they were cast (often known as reel-to-reel systems) raise privacy issues, if the order of voting can also be recorded. VVPAT printers that cut the paper after each ballot to form individual ballots can avoid this concern. If there are multiple voting machines it would be more difficult to match between the full voter list and the VVPATs. Alternatively, an attacker could watch the order in which people use a particular voting system and note the order of each particular vote he is interested in. If that attacker later obtains the paper ballot records she could compare the two and compromise the privacy of the ballot. This could also lead to vote selling and voter intimidation. In 2007, Jim Cropcho and James Moyer executed and publicized a proof of concept for this theory. Via a public records request, the two extracted voter identification from pollbooks, and voter preference from VVPATs, for a Delaware County, Ohio, precinct with multiple voting machines. Because both sets of records independently established the order of electronic ballots cast, they directly linked a voter's identification to his or her preference. Over 1.4 million registered voters in ten Ohio counties were affected. The situation was resolved before the next election by omitting the consecutive numbers on Authority To Vote slips from pollbook records. However, similar vulnerabilities may still exist in other states. Effectiveness concerns Also problematic is that voters are not required to actually check the paper audit before casting a ballot, which is critical to "verifying" the vote. While the option to look at the paper may provide comfort to an individual voter, the VVPAT does not serve as an effective check on malfunction or fraud unless a statistically relevant number of voters participate. Accessibility concerns Current VVPAT systems are not usable by some disabled voters. Senator Christopher Dodd (D-CT) testified before the United States Senate Committee on Rules and Administration at a June 2005 hearing on Voter Verification in Federal Elections "The blind cannot verify their choices by means of a piece of paper alone in a manner that is either independent or private. Nor can an individual who has
