I live in the precinct adjacent to teacherken in Arlington, VA. I got up very early (for me) this morning to get voting out of the way. In 2006, I got in line to vote at 7:15 a.m. but did not vote until 8:00 a.m. and I was in the 300-350 range of voters.
This morning, I went to vote at 6:50 a.m. (just about 25 minutes earlier). Turnout on the flip.
I was the 101st person to vote in the Democratic primary. I didn't see a Republican sheet tally because, well, this is a very heavily democratic precinct (85-15 Kerry, I believe).
The line was not very long - I voted by 7:05. The real holdup was that there was only one table checking in names, whereas in general elections, they have two tables (A-K and L-Z). There was only one page of voting - Presidential - so it took literally 10 seconds to vote via touchscreen (yuck). You had all 6 machines to yourself, but you were assigned to a particular voting booth.
Note: one election worker was an Elizabeth Kucinich look-alike.
I made my mark for Obama and headed out (to look for my turnout report from 2006).
Posting this as an FYI. Looks like turnout is a fair bit lighter in my precinct than 2006. My precinct is fairly older (not many younger couples with children, no student population to speak of), and probably 80-85% white. I think I was one of only 2-3 people in a line of 20-25 or so under 40 years old.
