I listen to talk radio sometimes during the day and catch parts of Limbaugh's show now and then. I'm not a "dittohead," but I will say he does make some good points from time to time among the blather. I don't always agree with him but sometimes I do. I consider myself smart enough to know when he goes "over the top" about something. I think it's good to get a balance of both sides of everything before forming an opinion.
To all the Rush name-callers, consider this: He does 3 hours of radio every day without a script and completely off the cuff, and still makes for an entertaining listen. Not many people can do that, and certainly an "idiot" couldn't.
To me the most interesting fact about Rush Limbaugh is the number of people who are total experts on him, but they say they NEVER, EVER listen to him.
