I love Duane as an artist and a performer, but that he's polling so high means that people have learned all the wrong lessons from this presidency. You can't wrap up an ideal political candidate in flashy promos and catch phrases.
He's at 50% "I don't know" because most of them don't know if he has any qualities to being a good politician.
They aren't dismissive because he's a super star. Johnson hasn't shown any understanding of history or political acumen and he's not advertising that. It's just a funsy question.
