On Wednesday night, all major broadcast networks will air Barack Obama’s half-hour campaign ad., except for ABC, who attempting to protect its Wednesday line-up, failed to reach an agreement to air the commercial on a different night.  

Later but too late, ABC did offer the Democratic presidential candidate the 8:00 p.m. EDT Wednesday slot, only to find that his campaign ad buy had already been finalized.  Instead, Walt Disney owned ABC will air the hour long ‘Pushing Daisies’ at the scheduled time.
