Oh, please. Stop that nonsense. He said he could fix the economy. It took forever to get an answer as to how. He finally gives an answer. After constant prodding. And even then it's clear he doesn't know how to fix the economy because his answer was so nebulous.
It's like saying, "I don't know anything about fixing a car, but the first thing I'd do is find out what the mechanic knows, then I'd rotate the tires, change the oil, put in new plugs..."
But if you feel that he provided a full and deep explanation on how to fix the economy, then I can also understand how you feel that Kerry actually DID have a plan.
