 Prominent opinion columnists and anonymous Democratic Party voices say after bombing the debate that Biden should back out of being the presidential nominee. But after an energetic 2,000-person rally in Raleigh Friday, Biden supporters like 25-year-old Kendrick Green say they're not worried. I think he was good on the issues last night, but I think he was a little slow on his feet, which is like him. You know, he's not normally, you know, the attack person, but I definitely think that he definitely responded great, and I was impressed today.
