The Clinton campaign's explanation for the loan.

I thought this was a very interesting backstory to the Clinton loan. (Understand that this is the Clinton campaign's version.)

Short version: They were at rough parity through 2007, but Obama's slightly lower overhead (consultants, office supplies, parking?) combined with his incredible January fundraising turned into a big advantage in Super Tuesday TV.

"The campaign faced a strategic decision -- either attempt to match his TV . . . or lose," said a senior Clinton adviser, who spoke about the internal discussions on the condition of anonymity. "I would say given the result of Super Tuesday, it was the right decision."

Not mention of Mark Penn, the reportedly $5 million man. Of course, he may be the source.
