A more thorough explanation:

An influence district is a type of voting district where a racial or ethnic minority group does not make up the majority of voters, but still has enough influence to elect their preferred candidate with the help of some crossover votes from other groups. This is in contrast to a majority-minority district where the minority group makes up the majority of voters.

For example, let's say there is a voting district where 40% of the voters are Hispanic and 60% are non-Hispanic. Even though the Hispanic voters are not the majority, they may still be able to elect their preferred candidate if they can get some non-Hispanic voters to cross over and vote for their candidate.

Another example could be a district where 30% of the voters are African American and 70% are white. The African American voters may be able to elect their preferred candidate if they can get some white voters to support them.

Overall, an influence district is a way for minority groups to have a say in the political process even if they are not the majority of voters in a particular district.
