Campaign director perks

The Washington Post reported that the Dean campaign has decided to forego further advertising in this round of the primaries. There's more:

The New York Times says the campaign "has upended its advertising strategy. Dr. Dean, who last June was the first candidate to advertise, is now the only major candidate to be off the air right now, and his strategists said Wednesday night that they were in no hurry to return." Furthermore, Dean campaign officials "said they were only confident of having enough money to compete through next week."

But the kicker, sure to anger Dean contributors, is buried later in the article: Joe Trippi "forfeited a salary as a campaign manager but collected commissions -- said to be as high as 15 percent in some cases -- based on advertising buys."

Comments here question how a campaign can justify paying a commission to a manager who places buys for ads for the campaign? There are probably a lot of people who could place $40 million in ads, pick up their 15% fee ($6 million!) and lose both primaries. Do you really need to pay that high a commission to get that kind of service?
