Yes I'm registered to vote (my kids and husband too). And I'm an election judge, a job we take very seriously! I vote in all elections - the city and state ones are just as important as federal elections and sometimes have a greater impact on our day to day lives.
I got mad at my (military) son when he told me several years ago he wasn't going to vote in the presidential election. I told him he should esp. vote b/c that man was going to be the one to decide if he was sent to a battle field or not. For years, my vote and my husband's cancelled each other but that didn't stop us from casting our ballot.
I get annoyed with people who don't vote, don't take part in any "civil" discussion and debate of issues and then sit around and complain about the country. I guess I was just raised in an era when it was considered our civic duty to vote, serve if possible or volunteer (in our communities, Vista, AmeriCorps, Peace Corpse, etc). I don't think they really teach that in schools anymore.
