Treating joke parties like one bloc with similar motivations is a mistake. The person behind Binface strikes me as intelligent, quick-witted and knowledgeable on modern issues. I have little doubt that he'd rule well had he actually been elected.
It's like if there is a Twitch streamer who shrieks and does stupid stunts to impress 6-10 year olds, I'd be skeptical when someone says that hey actually they are also really a intelligent scholar and whatnot. Then why do they have to go for the cheap effects?
If you have proper policy proposals, you don't need a ridiculous bin on your face.
And if it's really just protest voting, then my original comment stands. You may accidentally elect him for some role and you have no idea what he would actually do because nobody cared about that part, just the protest joke aspect.
This is the first time he's passed 5% of the vote and he was the only other candidate on the ballot. It seems quite clear cut that these are protest votes.
All that being said, purely off of vibes, I agree with the parent comment saying he would probably not misuse his power if he were to get it, which I think is already good enough in terms of "having no idea what he would actually do".
Your comparisons are distasteful and strike me as someone who doesn't really know the man, and just tosses out preconceived notions at him. His messaging doesn't have any undertones of "look how much I'm better and superior than the bureaucrats, I'm just like you guys!". Frankly I'd say he's less like the average person than an average politician. Neither is his humour cheap, nothing like shrieking for 6 year olds that you automatically accuse him of.
He presents himself this way because it's what he's good at. He's a highly educated comedy and satire writer. Also, he runs as a single candidate and probably doesn't really expect to win - but he does take the political system seriously and wants people to be engaged with it.
Humor has always been with us. I don't see what makes it so horrible. If a story can drive a point through it, why can't political messaging? Why is making pertinant jokes about the current situation worse than reading bullet points off a list regardless of the argument being made?
If you have real proposals, it will be interesting enough without the "ha-ha, I'm so quirky, I'm so random" costume.
"build at least one affordable house?" Is poking fun of the other candidates that would not do such a thing. Not one affordable house. If he went and said that directly, it would likely be defamation. But as a joke he gets the rally of the people while the other candidates are none the wiser. Yes the people want to hear this, yes they want both affordable housing and to see it recognized that other candidates have other ideas, but that doesn't mean they're being tricked.
