While I would otherwise agree with the concept that any candidate for office should be reasonably prepared for their role, I just wanted to point this out because the US already did this, and abandoned it. The political machines of the Gilded Age were by all accounts just as described here, and they were awfully corrupt to the bone basically because the only qualification to gain office was to have enough money and connections to get on the inside of the machine.
A test of basic competency asked of candidates as they apply to run for office is probably a more equitable way to handle this than what you're describing.
