Amy Sullivan at Time compares the ad to the 1988 Willie Horton commercial (forgetting, apparently, that it was Al Gore who first raised Horton as a critique of Dukakis).
But how silly is this? How thin-skinned and desperate must some of Barack's supporters be to claim that John McCain is essentially speaking in code to warn against Barack as Satan? Look at the evidence: Well, the type style in the ad's text resembles that of the "Left Behind" series. And there's a weird orange light that glows in the ad. Case closed.
The silly season has, indeed, begun.
