The McCain campaign has released one of their stylistically flashier Web ads to introduce a new line of attack, tying the Obama campaign to ACORN (the Association of Community Organizations for Reform Now), and suggesting that the group, which supports voter registration for low- and moderate- income families, is involved in voter fraud. The ad also accuses Obama of "blind ambition."
