That would mean that two candidates that are both extremely close to you can have vastly different forces while two highly dissimilar candidates that are far from you get nearly the same force. That doesn't seem like a realistic model. If I am a Bernie Sanders voter I would be mostly indifferent if I got AOC instead, but I would have a strong view between a center-right and a far-right party.</div><div class="gmail_default" style="font-family:"trebuchet ms",sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:"trebuchet ms",sans-serif;font-size:small">It might be more accurate to see the force from a voter as linear with distance --- every voter holds an elastic band that follows Hooke's law.
