Casting your vote when election time rolls around is just the tip of the iceberg when it comes to participating in the political process, but for most of us, it's as far as we go other than placing a bumper sticker or a sign in our yards. Think back to the last time you walked into a polling place -- did the workers there have something in common? There's a good chance that most of them were senior citizens. Working the polls is an easy way for you to play a part.
You doubtless have strong opinions about who should be chosen to represent you, and you state those opinions when you vote, but you can get even more involved. If you like a specific candidate, call his or her local office and ask how you can help. You could find yourself making phone calls to potential voters, stuffing envelopes or coordinating fundraisers and rallies. It doesn't matter whether you're working for someone running for local or national office; they all need volunteer help to get there.
If you don't want to campaign for a particular candidate, consider the issues that most affect you and the pieces of legislation that your local and national representatives could vote on. Care about environmental issues? Worried about your Social Security? There are countless grassroots organizations and special interest groups devoted to a particular issue or category of issues. They work to get politicians interested in their cause and try to convince them to vote a certain way, and they need volunteers to help spread the word.
