Bear with me on this one ...
I loved the movie Pulp Fiction. In it, Jules and Vincent are stone cold killers. They do their job with cool nonchalance. But when something goes wrong they fall apart; they can't cope with changed circumstances. They're utterly helpless until Winston Wolfe rescues them. In summary, the domain over which they can be considered "experts" is very limited.
Another example is Charles Barkley, a great basketball player of the not-too-distant past. When someone questioned him about his off-court behavior, he said: "I'm not a role model... Just because I dunk a basketball doesn't mean I should raise your kids."
Same with Scott Adams. I like him as a cynical observer of the contemporary American workplace. As for who he thinks will win the election, I couldn't care less. And I surely don't won't let him influence who I vote for.
You can enjoy Dilbert without knowing anything about Scott Adams.
But he's confident that he will find aforementioned counter: "But as it turns out, Trump is probably the world’s greatest persuader. That’s why I predict he will win in a landslide"
