Barack Obama is said to be ready to reveal his choice for a running mate who will make a bid for Vice-President. Rather than wait for the Democratic Party convention to make the announcement, as is traditional, he will let supporters know his choice through a text message. In a move that is aimed squarely at appealing to the technologically savvy younger voters, this will be a presidential election first. "No other campaign has done this before," campaign manager David Plouffe said in the e-mail. "You can be part of this important moment." The Obama campaign has effectively used the Internet to rally an army of volunteers and raise over $340 million as of the end of June. CBC Story.
