New Hampshire (and Maine) appear in another article, "Campaign Ad War Focused on 14 States," which also mentions Oregon and West Virginia. According to the Wisconsin Advertising Project (warning: .pdf file), Portland, Maine, is the #36 media market for "overall number of presidential spots aired, 9/24-10/7," and Manchester, N.H., #47.
You two are likely right - NH is still a battleground (along with OR and WV), but just doesn't make the top ten.
