Almost all major broadcast networks are set to air Barack Obama’s half-hour campaign ad tonight. However, ABC will be “Pushing Daisies” instead.

In an effort to shield its careworn Wednesday schedule, ABC tried to convince the Obama campaign to run the commercial on a different night, the Associated Press cited anonymous sources aware of the negotiations as saying.

However, when ABC decided to make space for the Democratic presidential candidate’s ad, it was too late, as his campaign had already completed the buy. Thus, the network has no other choice but air its “Pushing Daisies” and go up against Barack Obama’s spot, which is due to be carried by CBS, NBC and Fox among others.

The Obama campaign acquired the half-hour time on the three above-mentioned networks for $1 million each. The commercial will air from 8 p.m. to 8:30 p.m. EDT on Wednesday, just six days before the much talked about election, which will bring Barack Obama and John McCain in a face-to-face (or vote-to-vote) confrontation.

The 30-minute spot will portray “the specifics of Obama’s plans to turn the economy around and get the country back on track,” according to a statement released by campaign spokesman Nick Shapiro.

Evidently, brief political ads represent the widely acknowledged method used by politicians in their indirect dialogues with their potential voters. And Barack Obama has proved very talkative in these so-called discussions. As his fundraising has reached $600 million, he is able to transmit his messages nationwide without being forced to count every penny. Throughout October, the Democratic presidential candidate’s campaign bought approximately $1.8 million worth of ad time on ABC’s schedule only.

The half-hour spot on Wednesday is due to run on Univision, BET, MSNBC and TV One as well.
