WASHINGTON, Oct. 18 (UPI) -- Democratic U.S. presidential nominee Barack Obama is swamping his Republican opponent in advertising spending, approaching an all-time record, observers say.
With ads running day and night in battleground states and in multiple venues, Obama, a U.S. senator from Illinois, is outspending Sen. John McCain of Arizona by a 4-to-1 margin after raising more than $100 million in September, The New York Times reported Saturday.
Obama is quickly approaching and is likely to surpass the all-time presidential campaign ad-spending record set in 2004 by U.S. President George Bush, CMAG, a service that monitors political advertising, told the Times.
"This is uncharted territory," Kenneth Goldstein, the director of the Advertising Project at the University of Wisconsin, told the newspaper. "We've certainly seen heavy advertising battles before. But we've never seen in a presidential race one side having such a lopsided advantage."
Obama's ad-buying blitz has given him a key ability to counter McCain's own television ad strategy of launching a series of highly negative ads attempting to tie the Democrat to 1960s radical William Ayers as well as a blitz of automated telephone calls attacking him, the Times said.
