Where is John Edwards?

Why isn't Kerry using Edwards more? John Edwards should be a key and central part of this campaign. Yet you never see him. If I'm the Democrats, I'm using Edwards everywhere I can. I have him making policy statements, appearing with Kerry, focusing on states like Wisconsin and Minnesota where Kerry should win but maybe isn't and states like Louisiana and Tennessee where Kerry shouldn't win but maybe could. Kerry clearly made the right choice with Edwards but he isn't using him like Clinton used Gore or even like Gore used Lieberman. The Clinton-Gore team was a tough ticket for many reasons but part of it is was that they were a team who came across as 2 complementary people. We just aren't seeing that with Edwards.
