I loved this Byron York anecdote from South Carolina:
I went to Barack Obama’s rally here, on Sunday night, with a Republican friend who had never seen the Illinois senator in action before. Watching the crowd of more than 3,000 fill up the convention center, watching the people send up waves of energy to Obama, and watching him play off that energy in a speech that was one of the best political performances anyone has seen this year, my Republican friend said, simply, "Oh, shit." He recalled the scene from Jaws, in which the small seaside town’s sheriff realizes how big the shark he’s tracking truly is, and says, "We’re gonna need a bigger boat."
Why is something so obvious to Republicans not clear (yet) to Democrats?
