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.
The Presidency is more than just delegation of duties.
Which is exactly why it’s a giant red flag if a candidate has no political experience.
As said on a conservative blog:
More than anything, what sustains him is the sense — true or not — that he’s outsourced his actual duties to more responsible actors. Ryan and McConnell write the bills; Mattis, McMaster, Kelly and the generals coordinate foreign policy. Occasionally POTUS pops up to say something provocative about North Korea or NATO’s obsolescence or a trade war with China but mostly he seems consumed with live-tweeting Fox News and settling grudges.
