Separate or overlapping groups?

The traditional view of the voting public seems to be something like the first figure, with a left, right, and center, or more generally, a pro, con, and undecided. The center or undecided may move about, while the two extremes remain fixed. A more general view is that the public consists of a large variety of opinions that coagulate to the well-defined pro and con, and a third group that is not committed to either island.


































The first figure is that of the three groups, the second figure is the illustration of the undecided group moving con, or right if you must.


































The third figure shows the summation of the three groups into the general populace, and the fourth shows what happens when they move con or right.

I still maintain that the left-right axis is still too simplistic a view of almost anything, but this is a simple model to which I plan to refer in future posts.
