Obama ads have bucks; McCain's have the bark

WASHINGTON (AP) — Barack Obama spent $3.3 million in TV advertising Monday. At that rate the Democrat will spend more than $90 million on ads through Election Day — more than all the money Republican rival John McCain has to spend on his entire fall campaign.

McCain's ad spending Monday totaled about $900,000, and the Republican National Committee weighed in with about $700,000.

The disparity between Obama and the Republicans is so wide that it has allowed Obama to spend in more states than McCain and to diversify his message by both attacking McCain and promoting his own personal story.

With national and state polls showing him building a broader lead over McCain, Obama has switched to a more positive pitch.

Last week, only 34 percent of his ads attacked McCain directly while virtually all of McCain's ads attacked Obama, according to a study by the Wisconsin Advertising Project at the University of Wisconsin-Madison.
