Well, okay, maybe it's anxiety over whether this year will be the one year there are actually lines and I get delayed. This year, there was some anxiety over how long it would take me, independent of the line.
You see, it's not that I was dumb and forgot to update my voter registration after I moved. In fact, last time I moved, the NJDMV forwarded my address change so that I didn't have to do anything about it. The dumb part was trusting that this time they would do it before the deadline. The smart part was checking that ahead of time, and on learning that it hadn't updated, researching all the rules for provisional balloting.
It didn't take long once I was there. I've never had a line more than two or three people long, and this year was no different. Filling out the affidavit to go with my ballot took a little while, of course. Then I opened the ballot, and discovered it was half marked already! (Provisional ballots are done on paper.) Fortunately, all the ones that were marked were the ones I was going to vote for anyway, so I just filled out the rest and went on my way. I would have requested a new ballot if it hadn't been what I wanted, but it wasn't necessary.
