Explain briefly the reasons for the low level of representation of minority judges

What will be an ideal response?

An ideal response would be:
When judges are elected for a city or a state, African American and Hispanic candidates sometimes find it difficult to get elected. African American and Hispanic voters tend to be concentrated in the inner cities or in certain geographical areas; thus, their impact is diluted in citywide or statewide elections. For example, in a state in which the population consists of 20 percent African American voters, 20 percent Hispanic voters, and 60 percent white voters, with five judges to be elected on a statewide basis, few if any African American judges or Hispanic judges will be elected.
