Thank you for clarifying that. Not being an American, I'm not entirely familiar with all the finer procedures of your system.
The point that stuck with me in this persons testimony though was that about 20% of the people coming to the polls ended up being these provisional voters. Also there was the situation that person, after person, after person, claimed that they had had their status changed. Not knowing the background, of course, one simply cannot make a determination on the matter. But something just seems like it's a little suspicious.
But then again, I suppose there's always the possibility that these people had all voted illegally in the past and now a new system had finally caught up to their scheme. (It's been joked that southern California would be deserted if they kicked out all the illegals.)
