A generic question about the US election

The turnout was just under 60%.
Is this 60% of the adult population or 60% of people registered to vote?
I'm asking because this is the same in Germany. We don't have any of this get registered to vote business, if you're a citizen you're automatically registered to vote as soon as you turn 18.

Right

- Now have 1,000 neatly cut flyers for Die Fabrik, only took me 45 minutes with the guillotine at work... raggedy_man is doing the big town drop on Saturday, others whishing to join in more than welcome. If you can distribute flyers at your college or wherever, catch me on Tuesday.

- Dippadoom™ for tomorrow night is done.

- Tomorrow: Finish work at 5:30ish, wander over to Midsummer Common to find a nice spot, take photos of the fireworks display and the bonfire. Hopefully will have met up with the Holloways, drive to Bourne for autumn_storm's Bonfire party, be merry, take more photos, drive back about 1ish. Sleep.

And now, to bed. Huzzah!
