Matt Groening is a leftist punk who celebrated the death of Richard Nixon. I usually like the show, but when they infuse leftist politics into the plot, I change channels.
The Simpsons have been mostly non-political, but they did do some serious jabs at Clintoon. (”Well I’m a pretty bad President”) and make other lefty jabs.
For example, once Bart and Lisa used Grandpa’s ID so they could have a job drawing cartoons.
When it was discovered, Lisa asked Grandpa “Why did you think you started getting checks in the mail?” And Grandpa said “I thought it was because the Democrats were in charge”
