I think it would be interesting to see plots of responses to each individual question for each candidate. That would show the spectrum of positions depending on the issue.
Some candidates may be, say, very conservative in one way while being very liberal in another way. Their "dots" may scatter all over the plot. Other candidates "dots" may really cluster close together.
I would tend to be very wary of the "cluster close together" candidates. They would be such as the "flaming liberal" or the "reactionary conservative".
