I live in Wisconsin and I registered a month ago with League of Women Voters on a college campus. Took about 5 minutes. I got confirmation that I would be on the voter rolls with a letter.
I then just walked across the street at the community college, walked in and voted. Was pretty easy but I made for sure that I cast my ballot properly. There was something in Wisconsin where you vote on the ballot in to me an odd way. There is a arrow, a split arrow, by the candidate's names. You then take a special marker and fill it in to make a whole arrow. It was then sucked into a machine. I kept asking to make sure it was initialed right and my line was thick enough, etc. I was really worried about my vote getting tampered with in this battleground state. I think the end result in this election will be very, very close in Wisconsin so I didn't do the absentee or mail in ballot and wanted to do it in person.
Took less than 10 minutes to walk there, vote, make sure my ballot was done right, submit it and walk home.
Done. Took about 25 minutes on the upper west side of Manchester, NH. When I arrived the line wasn't that long at all, maybe 10 deep in my alphabet bracket. When I left it was out the door. The registration line was also 10-15 people long the entire time. I spoke to the guy helping people insert their ballots into the machine and he said that he's been volunteering at the polls since 1988 and that the turnout so far is by far the biggest he's ever seen, even bigger than 2008.
Went this morning 25 minute wait plave was flooded with undesirables made a big show of voting for obama again and not understanding the basics of the polling machine and it did bother me that no one was asked for id and that my parents and sister were still on the voting roll even though they've all been dead for over a year
