Mystery of unsolicited White House emails continues

Trying to get at the root of how the White House got these email addresses and what motivated them to send them unbidden:

"I don't want my name on some list," Porta said. "You know, my wife and I really want our privacy. I don't want to be on any list where I may be getting further e-mails from other groups. That's the main thing. We don't want to be on a White House list. We're not Democrats, we're conservative Republicans."

Benjamin, who also described himself as a Republican, said he received the Axelrod health care e-mail as a pop-up ad while he was reading a blog. He said the pop-up must have been approved by his internet service provider, AOL.

"The White House wants to put out a message so they have a conduit to put the message out to people who haven't contacted them in any way," Benjamin said. "Therefore, they're using AOL the same way that a spammer would be. I'm not particularly interested in hearing from David Axelrod."
