You don't have to go to the polls erry 3 months, you have to represent yourself in area to effect the laws of your area.
If you want marijuana legal for medical use because a majority of people think it's straight, instead of congress or your senator, you can do that. lol.
Edit:
And also, if you're against the war and want to let them know, you can vote you're against the war and want it stopped. simple simple simple
It's better than carrying around picket signs and taking days off of work
