I don't care if it slows down the legislative process, I am firmly of the opinion that all politicians should be legally required to take a short exam designed by experts on the topic of any legislation they want to vote on (including things like basic understandings of the concept and potential consequences, both positive and negative, of the legislation), and any politician who fails isn't allowed to vote on that legislation.
Politicians shouldn't be allowed to vote on legislation that they demonstrably do not understand.
