Here’s a few snips from a WRAL story, in North Carolina, “Hundreds in Wake Cast Early Primary Ballots”:

Primary elections in presidential election years traditionally attract 16 to 31 percent of registered voters, but Bartlett predicted a turnout of more than 40 percent this year because of heightened interest in the tight Democratic race between presidential candidates Barack Obama and Hillary Clinton.

Under a new state law, first-time voters also can register at the early voting locations before casting a ballot at that polling place. They need to bring appropriate identification, such as a driver’s license with a current address or other government identification. The entire list of accepted identification and other procedures is explained on the elections board’s Web site.

And:

Early voting opened at designated polling places Thursday. Through mid-day Friday, 750 people had cast their ballots, Wake Board of Elections Director Cherie Poucher reported.

The process runs through May 3, and some polling places will have Saturday voting opportunities in addition to weekday voting. It is open to registered as well as new voters.
