Make Your Voice Heard - Find Your State or Federal Representatives
If you have questions about who represents you - from the Colorado General Assembly to the United States Congress - Project Vote Smart - has the answer, plus much more information. By entering your 9-digit zip code (and there is a link to the USPS zip code look-up, if you're like me and don't know it), you pull up a page of all your state and federal representatives with links to their biographical information. It also tells you when your representative is up for re-election and gives you that representative's NPAT ("Colorado National Political Awareness Test"), if it's been completed by the legislator in question.
