A cluster of hydrogen bombs that’ll wipe all of the USA without touching any of the bordering countries.
The answer was right there next to the question.

Sincere answer: Fred Hampton. There’s a reason they killed him. He was someone who could truly mobilize marginalized folks (and plenty of non-marginalized folks as well).
Wow, thank you for making me aware of Fred Hampton and what happened to him.
If you're not still angry about CPD assassinating Chairman Fred at home in bed, you should be. This isn't ancient history, this is practically current events. The effects and causes are both ongoing.

Just raze it and start over.

Spoilers for a game that came out in 2018, but at this point I'd take someone like Maki Harukawa. I know she's fictional and meta fictional as well, but I wouldn't blink twice if I heard that a mysterious teen took out various members of the government without any trouble.
Though I would also settle for someone like Tails from any of the games where he is at peak power in terms of confidence and brains. If he was suddenly able to run circles around the law, via loopholes and various past and present interpretations of law, to become president, I would have zero issue calling him my president.
Or at the very least, I'd love to see him build a robot that is good enough to fool everyone into believing it is human and having that do Tails' job, as that would be amusing. Especially when the fallout happens after it's found out to be a robot. At his peak, I can guarantee he could probably pull it off.
Batman. Not the George Clooney Batman but any of the others should be fine.
