Drink the Kool-Aid dude! How did he get in it? The sherrifs department came on him while investigating a drug ring.
Did it never occur to you that if his housekeeper (or her sleazy husband) was running drugs for *other* people, Limbaugh would naturally be interested in whether he might have seen or heard anything that, in retrospect, might be helpful to the investigation?
Furthermore, her "Limbaugh was one of my clients!" claim may well be an attempt by her to get herself off the hook by giving them a "bigger fish", whether or not he actually had done anything wrong. This is a problem the police run into all the time -- they catch a sleazebag in a crime, and the sleazebag makes up a semi-plausible story about someone "bigger" to trade for leniancy. In this case, the fact that the woman was Limbaugh's housekeeper makes her story plausible, *even if it's not true*.
There are so many possibilities you have utterly failed to even consider.
Untrue
However there is one possibility you refuse to consider. Drink the Kool-Aid, lay down, peace will come.
Good grief, if she was a major seller, how did she have time to clean houses (and why did she need to?) If I knew somebody working for me was involved in drugs, I'd be scared to have them in my house with access to my stuff. (They could rob you blind.) Also, it's hard to imagine Rush being good pals with a chambermaid. I picture his friends as being several intellectual levels above that particular profession.
