When he was with MSNBC he repeatedly beat CNN and Fox for his time slot. RFD obviously is not mainstream but Imus is changing that. I know a bunch of people who are upset they don't get RFD, because of Imus. Another point is that Imus will bring on a guest and reference an interview from earlier in the show and almost every time the person, will say, "yeah, I heard that" or, "yeah, I was listening." And I am talking about senators, congressmen and well known media members.
You have no ratings numbers. You have no facts of any kind. Just a bunch of fluff opinion that Imus has, "no ratings". I watch and I know a bunch of people just like me. And I am just one person from a small town in Maine. Imus has a huge following and you are just showing your ignorance on the subject to suggest otherwise. You don't have much of a point if you have to exaggerate it.
