Voter ID might also help prevent double-voting by someone who is registered in two states. In 2004, a comparison of the voter registration rolls in North and South Carolina by the Charlotte Observerfound more than 60,000 people who were registered in two states, at least 180 of whom were listed ‘as having voted in both states in either the 2000 or 2002 general election.’

In New Hampshire, three of [ James O’Keefe’s ] assistants visited precincts during the state’s January 2012 presidential primary. They asked poll workers whether their books bore the names of several voters, all deceased individuals still listed on voter registration rolls. Poll workers handed out 10 ballots, never once asking for a photo ID. The ballots were immediately given back, unmarked, to precinct workers. New Hampshire Governor John Lynch James , who had vetoed a state photo ID bill, sputtered when asked about O’Keefe’s videos, focusing on the messenger, rather than his message—that polls are dangerously vulnerable to fraud. ‘They should be prosecuted to the fullest extent of the law, if in fact they’re found guilty of some criminal act,’ he roared.

One of the witnesses before the New York grand jury described how he led a crew of eight individuals from polling place to polling pace to vote. Each member of his crew voted in excess of 20 times, and there were approximately 20 other such crews operating during that election. This extensive fraud could have been stopped if New York required voters to authenticate their identify at the polls, and there had been poll watchers making sure that election officials were verifying voters’ IDs. The grand jury explained that ‘the ease and boldness with which these fraudulent schemes were carried out shows the vulnerability of our entire electoral process to unscrupulous and fraudulent manipulations.’ As a recent, thousands of fraudulent votes were cast in New York legislative and congressional elections.
