Term Limits is key. This is service, public service. The deep state has to work hard to corrupt incoming politicians. Once they have managed to bribe/extort/blackmail a pol, they do not want to lose them. Two terms would limit the corruption process. As far as knowing how to do the job, it is quite simple...follow the Constitution. Know the difference between right and wrong and do everything to benefit the whole country and all the citizens. This means reading every bill before voting. Eliminate omnibus bills. Single issue bills only.
