Gerrymandering doesn’t factor into presidential elections, because presidential elections don’t use districts. Gerrymandering only affects local and state elections. It’s how all of the crazy house reps have rock solid seats, for instance. But on the presidential scale, it’s voter suppression and swing voters, combined with presidential candidates focusing their time in expected swing states to reach that magic 270 electoral college votes.
I suggest you read the article you actually posted, because it supports what I said. Whoever wins the state gets all 38 electoral votes. It’s not like a 51/49 split has the votes split. Whoever gets 51% wins all of the electoral college votes. The congressional districts are gerrymandered to hell, but that’s because they determine house reps. Just like I said.
