No, he's not (and by the way, Springfield isn't in Oregon). But in this new clip uploaded to Fox's YouTube channel, Homer Simpson casts his vote for Romney.
If anything, Homer appears to be a swing voter. In 2008, he voted for Obama -- or at least tried to, before his voting machine cast his ballot for McCain instead. But his vote for Romney doesn't go so well -- Homer seems to have bad luck with Republicans going back to George Bush.
Check out the clip below to see why Homer chose to go for the GOP candidate. Perhaps Fox could have Peter Griffin endorse him next?
