Great/Terrible Ideas

I’m working on a project to try and distill the differences between canidate policy and reduce it to non-jargon, non-technical language and present it as a quiz driven by dilemmas. The users would respond to each dillemma by moving a slider. The slider captures not only alignment with a candidate, but allows for showing importance or strength of opinion. After making all the choices, the user reveals to themselves how aligned he or she is with both candidates.

For sources, I’m using almost exclusively the literature from straight from the campaigns.

I’ve run in to a couple of problems.
- How do I design questions for issues that are on one candidates agenda, but not the other’s?
- How do I account for other parties, such as the green party?
