Sen. Barack Obama’s campaign will air a half-hour special on CBS on Oct. 29 at 8 p.m., the network reported, adding that the campaign is in talks with NBC and Fox for similar deals.

he ad buy is the latest evidence of the Obama campaign’s massive campaign funds. Republican presidential hopeful Sen. John McCain, who is subject to the limitations accorded with accepting public funding, has been spending much less across the country than his opponent, and has not reported plans to make a similar primetime purchase.

“This is another indication, if there needs to be any more, that Barack Obama’s got more money than television time to buy,” Campaign Media Analysis Group head Evan Tracey said, according to James Hibbard’s The Live Feed.

Democratic presidential hopeful Sen. Barack Obama is outspending his Republican opponent Sen. John McCain in fifteen critical states as Nov. 4’s election approaches, new figures show.

The Obama campaign spent over $17 million in TV ads from Sept. 28 through Oct. 4, while McCain spent just under $11 million, a new study by the University of Wisconsin-Madison Advertising Project reported Wednesday.

On Monday, Oct. 6, alone, the Illinois senator spent $3.3 million on television ads, while McCain’s ad spending totaled $900,000.

In a presidential race mired in recent sharpened attacks, Sen. John McCain and Sen. Barack Obama will answer to undecided voters in Tuesday night’s town hall-style presidential debate, the second of three before Nov. 4th’s election.

The debate, held at Belmont University in Nashville, Tenn., will be moderated by NBC’s Tom Brokaw and will feature chosen questions from an audience of 80 undecided voters as well as a few questions sent in to Brokaw.

Unlike the first presidential debate, candidates will answer questions straight from voters, making it tougher for them to launch attacks against their opponent or to stray from the question to other talking points.
