I think it is, like most problems. I tend to favor the idea of term limits but while discussing this with a friend who used to work in politics, he made a good point I thought. His experience is that the staff change is the real problem in a political change. The ramp up time for a new staff is very long, the politician would not be able to get much done until the staff figures everything out, then it would be time to change again depending on the limit.
