To Kobach, that suggests were never actually residents of New Hampshire, and hence cast their votes illegally.
In fact, there's a far simpler explanation: Most of those voters were college students from out of state, who are perfectly allowed to register and vote in New Hampshire under state law — with or without a New Hampshire driver's license.
New Hampshire Public Radio did an investigation into this very question back in February. They received data on 5,903 same-day registrants with out-of-state licenses from the secretary of state's office.
Over 4,000 of them resided in college towns, suggesting they were simply out-of-state college students. The remainder were spread more or less evenly across the state.
Subsequent reporting appears to confirm this. On Thursday night, The Post's Dave Weigel put out a call for same-day New Hampshire voters with out-of-state driver's licenses to tell their stories. He heard from three of them — college students from out-of-state — within an hour.
According to New Hampshire law, college students may register to vote either in the town where they're attending school, or in their home town. A New Hampshire driver's license is not a requirement for registration or voting in either case. Proof of residency may be established by government photo ID or “any other proof accepted as reasonable” by elections officials, including “forms issued by your college or university.”
According to Kris Kobach, the prevalence of out-of-state drivers' licenses is “proof” of widespread voter fraud. In reality, it means nothing.
