The Republican Party has been using a grab-bag of strategies to counter Obama’s policies over the past month. They rail against the stimulus package for its (supposed) pork. They hammer home their points with gimmicky videos and props. They speak in warrior rhetoric and revel in heroic, fighting-man stunts. But if there is one strand running through all these strategies, it is that they evoke a discomfiting feeling of deja vu. We’ve seen this stuff before: The GOP is currently reliving John McCain’s presidential campaign. The return to the strategies of their fallen candidate may be the saddest illustration of the current state of the party.
