I'm always willing to look at term limits, and there are good arguments for them. But inherent in that debate are some arguments against them as well.
In arguing for them, we tend to blame career politicians and the corruption that comes with the power.
But how would we deal with kamikaze ideologues, willing to run for office once and "do what's necessary" for their cause? Imagine a congress full of people willing to say and do anything to get elected in order to fulfill a "mission", without the threat of electoral oblivion hanging over their heads? It seems to me that term limits would attract ideologues like flies. For what other reason would someone run for office, other than to fulfill what they believe to be their civic duty? How many Leftists are willing to say and do anything in order to create the desired results of their "civic duty"?
As it stands, the only non-violent power we have over politicians is the threat to remove them from office if they do not enact our will. Take away that threat, and what leverage do we have?
ETA: BTW, WTH. SpellCheck is your friend.
