Reply #66: I already provided my interpretation

Obama's talking about things like the fight between Hillary and McCain over the Woodstock memorial. He's talking about the Swiftboating of John Kerry.

Instead of talking about the issues that matter, we've been fighting over events from the 60s that hold little relevance today. Obama has talked quite a bit about not spending our time looking backwards and this is just another way of saying the same thing.
