Above, a clip just released by FOX. I thought the Simpsons creators got it wrong in 2008 when they had Homer voting for Obama, so this one comes closer to the mark (though I still think they have his motivation wrong; Homer's a Republican Party Reptile who couldn't care less about government-run health care).
Note the dig at Chinese sweatshop factories right at the end of the clip. The suicide nets are a reference to this.
