Adding that it's perfectly sensible that we all incorporate "dumb reasons" into our criteria for picking a candidate. A lot is unknown and unknowable about a candidate and what they'll do, and so we incorporate basic personality-related information into our decision process. But while we use that information to make our choice, those personality characteristics just aren't important in and of themselves. "The kind of guy you'd like to eat a muffin with" is information which might help you determine whether you trust a candidate to do what they claim they'll do once they get in office, but quality muffin eating time isn't an important skill for a president to have.
So, yes, candidate skills matter, but we shouldn't confuse candidate skills with presidenting skills.
