I recently ran across a teabagger complaining about all of the "Messiah" imagery associated with Obama, who challenged all comers to google "Obama messiah" images to prove his point. (I did go look -- what I found was more than half of them were right-wing mockeries, so I guess I'm not concerned.)
Then today there's a "Free Romney Bumper Sticker" ad on the top of DK. Odd, but I click anyway -- any time the Mittster offers to spend money on me for my vote I'll be sure to make him put out! -- and this is the image I find after filling out the form...
I hesitate to call it a dog whistle because it's so blatant. For those who can't see it, the photo is of Rmoney from behind, head bowed and left arm raised toward a light streaming down toward and over his head. The crowd is sitting silently, as though he might be leading a prayer or offering a benediction. He looks like a televangelist... or a messiah.
