Gromit is a ficitonal character from the series Wallace & Gromit by Aardman. Gromit is Wallace's beagle sidekick. While silent, Gromit undeinabley has a strong personality that shows through his expressive facial expressions. He is sensitive and intellegent, making him the brains of the operation when it comes to Wallace's adventures. Moreover, he is both faithful to Wallace but cautious of his whacky inventions. This combinations make Gromit a great friend who can both support and excercise concern for Wallace's safety. I beleive he would be a good candiate as a world ruler due to his kind hearted and clever nature. He will have empathy for his people, while also having a level of caution when he rules in order to keep his citizens in check.
Honestly, Gromit would likely not run for ruler of the world. However, with the encouragement of his peers, I can see him being a worthy candiadate. His kind heart would strive to make the world a better place. Gromit is also a lover of plants and gardening. His platform would place emphasis on climate change, and helping the planet.
