Term limits? You mean keep folks like Henry Waxman and Sherrod Brown and Sheldon Whitehouse and Barney Frank...and a whole list of others from being 'established', with experience and wisdom?
No thanks...I'd rather struggle with the bad ones than lose guaranteed GOOD ones.

(UNLESS we change the entire system of choosing candidates to eliminate most of the power brokering and nepotism... I can design that, but the 'system' has its own built-in safeguards against any changes that interfere with its habits.)
