I'm not sure what your point is.

Edit: thank you for the clarification. I don't see anywhere in the article where they imply these racial groups are voting in blocks. They seem to be breaking down individual voting power by race.

Taking an average doesn't imply voters vote in a block, it is simply quantifying the average disparity.

The unstated assumption about voting power is that all persons of a particular minority group are the same and have the same voting power. That's absolutely false unless you assume all people of that minority group vote the same. A black person in California has different voting power than one in South Dakota. The important indicator of voting power is not race, but location.
