WASHINGTON (AP) -- Presidential candidates Barack Obama and John McCain are criticizing each other in new television ads.
McCain portrays his Democratic opponent as a product of corrupt Chicago machine politics. Obama says McCain's proposal to deregulate health care could have disastrous effects like deregulation of Wall Street.
The negative commercials announced Monday come as the two candidates are locked in a tight race with six weeks until Election Day.
