We're not going to barrage you with VOTE! messages, but seriously, if you'll be 18 by November, you should vote. There's all this depressing news out there about how the "youth vote" is going to drop a lot in 2012, but we don't want to hear it. Even if you are SURE your state is going to go one way or the other, your vote DOES count. Get to the polls. (Lecture almost over.)
If you're not 18 yet, there are still lots of things you can do! This is your future to shape, and we know there are at least a few issues that you're passionate about. A good place to go to find out where candidates stand on the topics that matter to you is Generation Opportunity. They break down the issues, help you register to vote and let you send petitions straight to politicians to create change.
Generation Opportunity also has great guides to writing letters to your local newspaper editor, calling in to radio shows, organizing local events and speaking up at a town hall meeting, among other awesome ways to jump in.
No excuses -- this is a road map for getting involved. Go for it.
