I wouldn't impose mandatory retirement age on congressmen, but think there should be a age limit for the presidency and committee chairs. I think this is not particularly controversial.

What people hate but I strongly believe in is that we should pay people a stipend to run for office. And we should pay congressmen and senators more than we do. And give them a full years salary when they leave office. Seriously guys producing webshit for FANNG companies are making more than their congressman.
