Political scientists distinguish between two kinds of issues in elections campaigns: “positional” issues (voters have sharply divided and incompatible

views) and “valence” issues (voters agree on goals but are divided on the best ways to achieve them). In a race between the incumbent and the

challenger for state governor, a marketing survey found that if the incumbent focused on positional issues, she trailed the challenger by 5% if he

focused on the same kind of issues, but she led him by 5% if he concentrated on valence issues. If she focused on valence issues, she trailed him by

15% if he focused on the same kind of issues, but she led him by 25% if he concentrated on positional issues.

What does P represent?
