Donors
Some figures here.
You haven't mentioned "bundlers," which apparently accounted for over $60 million of "individual" Obama donations (an even larger amount of McCain's funds came from bundlers).
Nor do you mention the amount of money that went to support Obama's campaign effort that was not directly donated to his campaign coffers. The tens of millions spent by special interest 527s went somewhere, after all, and it wasn't all to House and Senate candidates.
The image of most of Obama's donors being millions of little people scraping out their piggy banks is a myth.
Obama's transparency in fundraising leaves a lot to be desired, and now that he's elected, odds are good that's where it's going to stay.
