Daniel Henninger thinks that the Democrats have plenty of time to exploit a failed surge, if it in fact should fail. Insisting or assuming that it can’t succeed is, politically, a high-risk strategy. The only plausible reason for taking the risk is that they’re utterly convinced it can’t succeed. I think that’s called defeatism. There are other consequences that might follow from a political strategy informed by defeatism, but I’d rather not think about them.
