Biden and Obama Back Together Again

From CBS News' Arden Farhi:

(GREENSBORO, N.C.) - After campaigning for nearly a month on his own, Joe Biden played second fiddle today in Greesnboro, introducing his running mate at an outdoor rally before an estimated crown of 20,000. The two democratic nominees last appeared together after the Democatic Convetion on August 31 in Battle Creek, Mich.

Biden's opening remarks focused on Barack Obama's qualifications as a commander in chief and steward of the economy. Foreign policy and the economy were two themes of last night's presidential debate.

"America saw a person last night, the person sitting here to my left, and they didn't just see a winner last night, they saw the next commander in chief. They saw the man with the vision, the strength and the judgment to be commander in chief of the United States of America," said Biden while introducing Obama. He used the phrase "commander in chief" repeatedly throughout his speech.

On the economy, Biden attacked John McCain. He called his Senate colleague "out of touch," as he often does.

"John McCain's silence was deafening on the middle class. The words never parted his lips one single time," Biden said, referring to McCain's use of the phrase at the debate. Earlier today, the Obama campaign released an ad criticizing McCain for failing to say "middle class" last night.
