It would sure push things that way, because the liege-slatterns won't be as familiar the ins and outs of agency connivances. Of course, that's not always a bad thing.
Re total time, who would have the wisdom to deny Henry Clay, Patrick Henry, or Jesse Helms on the strength of too much time in office, much less Antonin Scalia, Story, Fuller, or Taney? To allow that much latitude for whimsy is to engage in a poor understanding of history.
My opinion of term limits is mine, and all should develop their own, which may or not be similar to mine.
I do not believe term limits is the answer to our woes. It seems no matter who gains elective office the course does not change much.
Having read the replies, and with my tainted personal perspective, I think there is something that could have a greater impact. Prohibit all campaign contributions from organizations, businesses, PACs, Labor Unions and whatever other legal groups exist. All organizations are comprised of people.
Allow them to make their contributions solely as individuals. This would give campaign fund raising a transparency to see who is really pulling the strings & yanking the chains of the candidates and elected office holders.
At present we hold our disdain for the elected, not the puppet masters. We have got to identify the puppet masters. Only then can we keep them from putting their puppets in place.
