The statement that the cartoon depicts gerrymandering in a negative way is True.
What is gerrymandering ?
Gerrymandering is the practice of drawing electoral district boundaries in a way that gives one political party an unfair advantage over another.
This can be done by packing voters of one party into a small number of districts, so that they win those districts by large margins, while spreading voters of the other party out over a larger number of districts, so that they win those districts by smaller margins.
The cartoon shows gerrymandering negatively by depicting it as a savage beast.
