The good folks at Project Vote Smart have developed an interactive feature that quickly matches your opinions on critical issues to congressional candidates you'll be choosing in the November election. Think of VoteEasy as the eHarmony of political web sites.
First you enter the ZIP where you live. (You may have to enter your address to determine your U.S. House district.) Then you answer a set of 12 yes/no questions covering the important national issues of the day -- abortion, Afghanistan, immigration, gun control, etc. -- as well as how important each issue is to you. At each step the system updates the results, assigning each House and Senate candidate a matching score, (i.e. some percentage similar to you). When finished the system flags the politician that best matches your outlook. Click on the candidate's picture to see a profile comprised of biographical details, interest group ratings, campaign donations and voting record (if available).
Cool as VoteEasy is, you'll also want to consult The Bee's online Voter Guide. It contains biographical profiles of federal, state and local candidates running this November, plus their answers to specific issue questions posed by Bee reporters and editors.
