Democratic presidential nominee Barack Obama's half-hour campaign commercial is scheduled to run Wednesday evening at 8 p.m. on all of the major U.S.  Television networks except for ABC. The senator from Illinois this month arranged to buy tonight's 8 p.m. to 8:30 p.m. slot on CBS, NBC and Spanish-language network Univision as well as BET, MSNBC and TV One. Fox Broadcasting joined the field after Major League Baseball agreed to delay the start time of tonight's World Series game. However ABC executives said the earlier decision not to accept the Obama infomercial was due to the problem of filling the second half-hour of the 8 p.m. to 9 p.m. time period, and not for political reasons.

The 30-minute spot, which was announced in early October, will air six days before the election between Obama and Republican candidate John McCain. The campaign bought time on CBS, NBC and Fox for $1 million per network.

According to a statement from campaign spokesman Nick Shapiro, Obama campaign is a "program," and the half-hour will present "the specifics of Obama's plans to turn the economy around and get the country back on track." It is believed that the ad will show Obama sitting around a white kitchen table with four people/families he's met in the last 21 months of his campaign, each illustrating an economic challenge the nation is facing. He'll also share his personal story about his mother's death from ovarian cancer, how she spent her last days arguing with her insurance company about whether or not her cancer was a "pre-existing condition," a story he often tells on the campaign trail.

While most of the major networks had to change their schedules in order to fit Obama in, ABC will run an original episode of "Pushing Daisies," as planned.
