I already read about this and there is a HUGE flaw in the argument. New Hampshire doesn't require out of state college students, nor people of professions that are simply there to work short term like doctors doing residency, to get a New Hampshire driver's license in order to vote.
One of two things is true:
1) You didn't read the article, or:
2) You failed to grasp the argument put forth.
The article is based on a simple set of facts: only 7% of those "same day" voters obtained a driver's license, and only 3% registered a vehicle in New Hampshire. While that, in itself, does not prove voter fraud, it does call into question the same day arrival/vote of over 6,000 voters.
As for the add-on comment, there is a single military base (New Boston AFS) in New Hampshire. It houses about 300 people. Given that most military maintain, and vote, in their original home of record, it would have minimal-to-no influence.
By no means, does the article claim this is proof of voter fraud. But even a committed liberal such as yourself must admit that it does bear scrutiny. - unless, of course, you DON'T want to know the answer.
