I'm not even a Trump supporter, but this once again highlights how dumbfoundedly awful The Simpsons has grown into in recent years. It was already proven in 2016 that whenever the media blatantly encouraged anti-Trump vendetta, it caused that to be one reason he was elected in protest by people of being sick of being told what to vote for, and this show was one of the examples that caused it, clearly learning nothing now. The Simpsons is meant to just entertain and humour people, it's not supposed to be a political vacuum of bias. In fact, there were almost no jokes in this anti-Trump promo by them, so it doesn't even feel remotely like the show really

. And in the past when it has ventured into politics, as far as the classic era of the show goes at least, it kept things impartial and made fun of everything to therefore appeal to everyone.
Mess and it's supposed to be a Treehouse of Horror halloween episode, is the joke supposed to be that Trump's presidency is "scary"? It's just so preachy and transparent, and ultimately won't do anything to stop people voting Trump.
