WEEI has a small problem. They can cover it up by dinging Minihane for a long suspension or letting him go, but the problem remains.
That's what D&C is as a show. They are kinda racist, homophobic highly misogynistic assholes, that is the whole point of the show. That a sponsor chose to take action on this one incident hurts them, but the show is one of their highest rated because that's a big chunk of the talk radio audience, Misogynistic, racist, homophobic angry at the world white guys. Their sponsors would prefer not to be associated with that likely (since they sell to a much wider audience), but WEEI isn't going to compete in AM talk radio if they dump D&C for measured smart sports talk, there isn't a market for it on drive time radio.
