Obama has email list of TEN million, used as collateral

"He's going to be the first president to be connected in this way, directly, with millions of Americans," Trippi said.

The nucleus of that effort is an e-mail database of more than 10 million supporters. The list is considered so valuable that the Obama camp briefly offered it as collateral during a cash-flow crunch late in the campaign, though it wound up never needing the loan, senior aides said. At least 3.1 million people on the list donated money to Obama.
