WASHINGTON (CNN) - When it comes to campaign commercials, Sens. Barack Obama and Hillary Clinton are going where no candidate has gone before.
Obama and Clinton have spent a combined $110 million on TV ads to this point; we've had a race that's literally gone on since last summer for ad spending," said Evan Tracey of TNS Media Intelligence/Campaign Media Analysis Group, CNN's consultants on campaign commercials.
"We're beyond what has been record spending in previous presidential nomination campaigns. John Kerry spent close to $20 million to get the nomination four years ago. Barack Obama's already approaching $70 million."
