Former U.S. President Bill Clinton&#39;s convention speech nominating President Barack Obama for a second term left Morgan star-struck: &quot;Already the best speech of either convention,&quot; the prime-time talk show host tweeted. &quot;An oratorical genius right up there with Churchill, Kennedy, MLK and Mandela.&quot; (AP Photo/Jae C.
