Actually, I think the Simpsons premiered on the Tracy Ulman Show in the early 90’s after Reagan, but that doesn’t change your point. If you don’t know who the Simpson are today, you have been asleep for the last 25 years.
I liked the Tracy Ullman show.
Groening was a cartoonist for the left wing alternate press before the Simpsons. He was a leftist from way back. The Simpsons may occasionally poke some leftist icons but generally it fits in just fine with leftist Hollyweird.
