What the fuck happened in North Carolina?

Keith blogs on what's on tonight -- at 5 pm Pacific, 8 pm Eastern, and then at 9 Pacific, Midnight Eastern:

NEW YORK— With news this morning that the computerized balloting in North Carolina is so thoroughly messed up that all state-wide voting may be thrown out and a second election day scheduled, the story continues.

Tonight on 'Countdown,' we'll examine the N.C. mess (which would not include a second presidential vote), new fuzzy math in Nevada, allegations against the Democrats in Pennsylvania, Ralph Nader's news conference, and the other voting developments as they occur. A Stanford computer expert will address the vulnerability of the Optical Scanning system (and answer the question: which is easier to hack, electronic voting or exit polls?), and Newsweek's Jonathan Alter will join me to report on the reporting.
