This is a cool site. There is a 2-part quiz. The first quiz seems useless when you are doing it, but it informs the second part that measures the strength of your opinion on these issues. The first part measures how important to you different categories of issues are. You assign values until you use up all of your “points”. I think that this makes you focus on which issues you care about and how much. The second part is a Likert scale from strongly disagree (oppose) to strongly agree. The statements are based on general differences in policy proposals/support from politicians.
The result pairs you with politicians and tells you how well you match. I was 87% Nader. I’m not surprised. I’ve even voted for him in the past (I’m a 3rd party guy). It’s tough who to identify with when you are middle of the road. Also not surprisingly I was a 65% match with Obama and 33% with McCain. That about sums up my opinion on all of them 🙂
Obviously, there is more to think about than how well you match overall.
