Want to influence the election by more than your 1 vote?

Go to your polling place at oh, let's say thirty minutes before the polls close. Here in California it's 7:30. Get your ballot, just sit in the booth, and just stay there. Do nothing. Don't talk. Don't make noises. Don't vote. Just stand there.
Chances are that you'll be in there for at least 10 minutes before a poll worker comes by and asks if you need "assistance". Kindly ask them to go away or just feign ignorance about these electronic voting machines and then ask them for privacy. You might want to use the restroom beforehand and bring a snack into the booth with you.
What happens when you invoke this kind of false indecision, since you're allowed as much time as you need to make your decision (see old people), is the machine you're using becomes tied-up indefinitely. This can prove strategic if the political demographic in your polling location differs from your own. People in line when polls are closed are still allowed vote, but I'm sure the long line you've helped to create will discourage a few away.
Anyways, I'm not sure how legal this is, but it sure would be hard to catch. Especially if you get a few of your friends in on it (again, see old people).
