Ford Fessenden on voter registration in Florida and Ohio, in The New York Times:

A sweeping voter registration campaign in heavily Democratic areas has added tens of thousands of new voters to the rolls in the swing states of Ohio and Florida, a surge that has far exceeded the efforts of Republicans in both states, a review of registration data shows.

The analysis by The New York Times of county-by-county data shows that in Democratic areas of Ohio - primarily low-income and minority neighborhoods - new registrations since January have risen 250 percent over the same period in 2000. In comparison, new registrations have increased just 25 percent in Republican areas. A similar pattern is apparent in Florida: in the strongest Democratic areas, the pace of new registration is 60 percent higher than in 2000, while it has risen just 12 percent in the heaviest Republican areas.

While comparable data could not be obtained for other swing states, similar registration drives have been mounted in them as well, and party officials on both sides say record numbers of new voters are being registered nationwide. This largely hidden but deadly earnest battle is widely believed by campaign professionals and political scientists to be potentially decisive in the presidential election.
