Hours after Barack Obama selected Biden, Senator John McCain released a commercial about Biden.

Narrator: “What does Barack Obama’s running mate say about Barack Obama?”

ABC’s George Stephanopoulos: “You were asked, 'Is he ready?' You said, 'I think he can be ready but right now, I don't believe he is. The presidency is not something that lends itself to on-the-job training.’”

Joe Biden: “I think that I stand by the statement.”

Narrator: “And what does he say about John McCain?”

Biden: “I would be honored to run with or against John McCain, because I think the country would be better off.”

John McCain: “I’m John McCain, and I approve this message.”
