It's not as bad as it sounds, as poorly written in the headline and beginning of the article. Cumulative voting is a known method. Every citizen's vote counts the same as every other citizen's. Except instead of getting one vote that has to be for one person, you get multiple votes to apportion among your favorites, but you can still put them all towards one candidate.
I'm not a fan of this method, but it is generally valid.

What I don’t see is how does this guarantee a Hispanic official? If the judge is so afraid that the reason no Hispanic has ever been elected is because Hispanics don’t have enough votes, then how will this fix it? It assumes that People are not individuals, they are groups, think in groups, vote in groups and all group members have the exact same political needs. So, is the idea that the white majority will vote for Hispanic if they can split their vote? What if the majority of whites don’t split their votes?
