What does the trend toward descriptive representation suggest about what constituents value in their legislature? How might Congress overcome the fact that such representation does not always best serve constituents' interests?

Legislatures have been decided by identity politics which has gained prominence in latest years.

Explanation:

Descriptive representation is first of all a symbol of identity politics in legislature which has now become increasingly common as the people have begun to question the legitimacy of the participant democracy of representatives.

Descriptive representation is the idea that a group must elect and individual who would be like them and have their experiences in their life to represent them in legislature.

Of course, this does not mean that the person would be an ideal candidate.
