"It’s unfortunate that the World Series’ first pitch is being delayed for Obama’s political pitch," RNC spokesman Alex Conant said. "Not only is Obama putting politics before principle, he’s putting it before our national pastime.”
Major League Baseball has agreed to a request from Fox to delay the start time of Game 6 of the World Series (if a Game 6 is necessary) so the network can air the 30-minute Obama spot, a Fox spokesman confirms to CNN. The Illinois senator has also bought similar time on CBS and NBC, set to begin at 8 p.m.
“FOX will accommodate Senator Obama's desire to communicate with voters in this...format," Fox spokesman Scott Gorgin said. "We are pleased that Major League Baseball has agreed to delay the first pitch of World Series Game 6 for a few minutes in order for FOX to carry his program on October 29."
It's the first time a presidential candidate has bought that length of airtime on network television since Ross Perot purchased several 30 minute blocs in 1992.
"This is a big platform, this is a big megaphone, the interest level is clearly there and people will watch," Evan Tracey of Campaign Media Analysis Group, CNN's consultant on campaign advertising said.
The October 29 game will now start at 8:38 instead of 8:20.
