As you may recall, he had to be talked into running against George Allen in the current Senate campaign. He really didn't want to do it.
So now he has to go to Charlotte and give a speech to the assembled Democrat delegates and make his strident pitch for a job he has no interest in.
He delivered his lackluster speech. No one paid attention. He went off to get a hot dog.
You can look for his speech on YouTube. But you won't find it. Too much of a bother to upload, obviously.
So why is he bothering to run for the Senate?
