I think I have a better idea about the redesign of the questions. What if every line you had to agree or disagree with were an actual quote from an actual politician's speech or writings? And I mean an important speech, not just an off-the-cuff remark. It would have to be something well thought out.

Of course, there might still be some difficulty. A lot of speechmaking is deliberately ambiguous. But at least it would simulate what we all have to do in real life when we decide whether we're going to vote for someone or not.
