Over the years I've come to the conclusion that with only a very few exceptions, nobody who aspires to elective office should be permitted to hold an elective office.
@lauren This is a real over-think-hole. If not those who want office, then who? Obvious alternatives all seem at least as bad (lottery, draft, heredity, seniority, civil-service test).
I'll bet there's a ton of political science literature on the topic. Oh good, homework.
@Haldane You definitely don't want to overthink this one.
@lauren Yeah, I know. It's a character flaw.
