The congressman does not have to be an expert, they have to be able to become WELL INFORMED on anything in which they have policy directing power.
As an IT director I dont have to be an expert in python, ruby, networking, exchange admin, etc... That's why I hire staff who are experts in their areas. They inform me as the best direction to take.
I set the policy, understand to a certain level (rather technical, but not for example CCIE level - thats why I hire CCIEs) what each person does.
But I would never stand up at a company meeting and say "I have no clue how our firewall is configured - but I think we should block all traffic to ports 22, 80 and 25 because that seems to be where all our attacks come to. (blah blah blah port knocking blah blah blah)
