I would have one of my political allies propose a bill that would fund universal secondary education, then when it is inevitably shot down, I would use my newly granted immunity to have anyone thay voted against it very publicly removed then I would have an ally propose a constitutional amendment creating public education and removing presidential immunity. Then I would resign, and my vice president would pardon me, then my vice president would push a bill, preventing the president from being pardoned for crimes commited* while in office.
