We know Homer is no liberal. He watches fox and gets angry about "aborted" space missions.

However, according to IGN, even Homer may have had enough. At ComicCon, there was a few clips from the upcoming season of The Simpsons. *Spoilers Below*
"The first clip is set on Election Day, with half of a Springfield street's storefronts decorated with Obama signs and the other side covered with McCain ones. Grandpa Simpson holds a sign that reads, "I Still Like Ike"; Mr. Burns stands on the opposite side with a sign that says, "Vote NO on the Magna Carta."
Homer checks in at the polling station looking to vote for governor, president, "anything that will take more money from our parks and libraries." Home can't squeeze into the first voting booth so he's sent to the handicap one since its wider. That booth has an electronic voting machine, which he soon discovers is rigged when his votes for Obama are recognized as McCain votes. When he threatens to report the machine, it opens up revealing a vacuum tube that sucks him inside. He gets sucked inside and then spat back out into the auditorium, where stamps Homer's head with a sticker that reads, "I Just Voted."
