The reason lack of political experience is only a giant red flag and not a disqualification is delegation. The President does not need to know how to do everything – they only need to be smart enough to know who knows how to do things, and delegate accordingly. I’d be fine with an amateur pitching in the Word Series if they could delegate the pitching duties to someone else, as long as I trusted their judgment about who that person might be.
That said, it’s still a giant red flag. I’m not excited about the prospect.
