Spoken like a true liberal.
Convention speeches are measured by their effectiveness. From the standpoint that Clinton stirred up the liberal base in support of Obama, I can't imagine anyone saying that he did not do a fantastic job. Are you denying that? If Clinton wanted Obama to fail, he gave the wrong speech.
What, specifically, was so great about the speech? I.e.: what were the greatest lines/moments, and what made them so outstanding?
Clinton wanted Chelsea to live.
He might also have wanted Soros to eventually support Hillary in a 2016 Presidential bid too.
