Well, crap. Now you made me go research term limits just so I could respond without looking like a complete idiot. Here are the pros and cons on term limits: http://www.balancedpolitics.org/term_limits.htm
I’m inclined to agree with the pros.
It would be interesting if there were an amendment that allowed an exception to term limits if the incumbent had 90% of the popular vote, or some other insurance that the vast majority wanted to keep a certain person in office. Hmm…my mind is racing with possibilities.
