Lakoff uses this model to answer the central questions framed above - why is there such clear grouping on issues that separate liberals and conservatives, and, conversely, why don't we find more issue-by-issue voters? Lakoff claims that one's take on any given political issue is largely determined by which model one adopts. Thus, in Part IV, "The Hard Issues", he tries to demonstrate how the liberal and conservative worldviews outlined above lead to typical liberal and conservative positions on a wide range of issues, including taxes, the death penalty, environmental regulations, affirmative action, education, and abortion.
