"Power tends to corrupt... Great men are almost always bad men."When we last left 18 year Utah Senate veteran Bob Bennett, he was sobbing his way out of office, having been ousted by voters in the state's GOP convention in the midst of what Bennett called the "toxic" atmosphere of anti-incumbent dissatisfaction. Three terms in public service should be enough for any citizen, but given the money and power involved it's no wonder that Bennett is far from the most extreme example of the American Political Tick.
Lord Acton, 1887
Experience shows that our politicians will generally not voluntarily give up their powerful positions in government; very few resign unless clearly facing voter rejection or perhaps under cloud of scandal, and even then they sometimes have to be forcibly shown the door. Many would-be reformers call for imposed term limits as a solution, but such legislation must be sponsored and supported by the very men and women taking advantage of the system, so the term limitists probably shouldn't hold their breath.
