The fuck it is, if 8 years is enough for the president it's enough for Congress, Senators, and the SC Justices.

If we can pass down the office of president every 8 years there's no reason we can't do the same elsewhere, does it take a decade to learn how to vote or something? Are we lacking in judges?

There are other levels of office, there isn't going to be a shortage of experience just because we require term limits. Even if there was I'd prefer an inexperienced person than someone who sits on their hands all day and just votes according to their oligarchical masters whims.
