How to Find Out Obama's Running Mate

Campaign manager David Plouffe says in an email to supporters they can receive an e-mail or a text message the moment Obama makes his decision.

It's an attempt to harvest email addresses and phone numbers under a grassroots conceit.

"You have helped build this movement from the bottom up, and Barack wants you to be the first to know his choice."

"You will receive an email the moment Barack makes his decision, or you can text VP to ------ receive a text message on your mobile phone."

The e-mail contains a fundraising solicitation link.
