vote
Voting is great - do your duty as an American or get off of my website... :)
Here are some tools to help you keep tabs on who is voting how. Fun fact: we live in a representative democracy, at least for now!
Also, download the Congressional Record app for your smartphone - you can even drill down to all the specific legislation! Just look for "Congressional Record" on your app store of choice :)
Seriously, though, please get involved in politics. If you're old school, you can just call the Main US Capitol Switchboard, punch in your zipcode and they'll connect you to your reps so you can ask them WTF they are doing ;) 202-224-3121
