Biden's Audition?

Is he auditioning? His office just sent around his star moment from yesterday's Petraeus/Crocker hearings:

During questioning in yesterday’s Senate Foreign Relations Committee, Chairman Joe Biden (D-DE) and Ambassador to Iraq Ryan Crocker engaged in the following telling exchange

SEN. BIDEN: Mr. Ambassador, is Al Qaeda a greater threat to US interests in Iraq, or in the Afghan-Pakistan border region?

AMB. CROCKER: Mr. Chairman, Al Qaeda is a strategic threat to the United States wherever it is, in my view–

SEN. BIDEN: Where is most of it? If you could take it out? You had a choice: Lord almighty came down and sat in the middle of the table there and said ‘Mr. Ambassador you can eliminate every Al Qaeda source in Afghanistan and Pakistan, or every Al Qaeda personnel in Iraq,’ which would you pick?

AMB. CROCKER: Well given the progress that has been made again Al Qaeda in Iraq, the significant decrease in its capabilities, the fact that it is solidly on the defensive, and not in a position as far--

SEN. BIDEN: Which would you pick, Mr. Ambassador?

AMB. CROCKER: I would therefore pick Al Qaeda in the Pakistan-Afghanistan border area.

SEN BIDEN: That would be a smart choice.
