What is political foil?

Political foil is a literary device in which a character's traits are emphasized by contrasting them with the traits of another character. In politics, a political foil refers to a person or group that highlights the differences or contrasts between themselves and their political opponents. It is commonly used in political campaigns and debates to differentiate oneself from the opposition and appeal to the voters. Political foils are often used to portray a candidate as a stronger or more viable choice by highlighting their strengths and highlighting the weaknesses of their opponents. The goal of a political foil is to create a clear distinction between the candidates or parties and to highlight the different values and policies that each represents.
