Guerrilla videographer James O’Keefe and his Project Veritas team have for years documented just how easy it is to commit voter fraud in states ranging from Minnesota to North Carolina. In 2012, his undercover exposés at the polls convinced the New Hampshire legislature to pass a bill mandating that voters show a government-issued ID — even college ID cards are acceptable.
If voters have no form of ID, they can sign an affidavit and still have their vote counted. The votes needed to approve the bill over the objections of then-governor John Lynch were provided by his fellow Democrats.
