A sizeable portion of Congress critters are in dire need of medical and psychological evaluation. When some are so old that they are having trouble even being ambulatory under their own steam, it’s time for them to go. I’m bordering on codger territory myself, but I’m astute enough to know my limitations. When they dodder in and have to consult their handlers (who usually sit directly behind them during hearings) on every little thing and have to read prepared talking points without any spontaneous input, this indicates their shelf life is expired.
