Final answer:
The underrepresentation of women in state and national legislatures is considered unfair and shows gender inequality in political representation.
Step-by-step explanation:
The fact that only about 20% of those elected to state and national legislatures in the US are women is considered unfair by many people. This underrepresentation of women in government is an example of gender inequality and unbalanced political representation. It is important to have more women in government to ensure that their perspectives and issues are properly represented and addressed.
