I voted 3-4 weeks ago and I'm really glad I did. Just drove past a polling location and the lines are out the door and down the block:
The SandCastle Queen reports she was at the polling location when it opened. The lines were pretty short at 6AM ;-) I'll be glad when this day is over. Local TV has been unwatchable as it seems nearly non-stop political ads.
Update: 2130: Driving by the polling site around 1830 the line took the dimensions of the red line. The Google Maps measurement tool puts this path at >1000 feet. At ~2100, 1 hour after the polls had "closed" (these people still get to vote), Media has already called the state for Trump & Clinton the end of the line stopped at the green dot (~650 ft).
This for a ballot with one question. Someone said the voter check in process was taking a couple minutes per voter and that was the bottleneck.
So the line advanced 350-400 feet in 2 1/2 hours.
P.S. This is one of the reasons I voted a month ago! Recall the six P's: Prior Planning Prevents Piss Poor Performance! I planned ahead and thus enjoyed my relaxing evening. You didn't and ... enjoy your queue! (I chose wisely!)
