From the October 18 edition of Premiere Radio Networks' The Rush Limbaugh Show:
RUSH LIMBAUGH (HOST): The Hillary campaign, the American left they take the campaign to the sewer and if you're going to respond that's where you're going to be. In the old arguments don't get into [an] argument with a pig or a fool because after a while people won't be able to tell the difference. But Trump chooses to respond. This is what it looks like. You can do one of two things: Trump can campaign and not respond to any of it and people get mad and all this defamation goes by unanswered or Trump reacts to it. I think it's classic to demand a drug test. I think it's classic. Everybody else thinks oh my God, oh my God like Josh Earnest the White House press secretary. Out there, you know how he's reacted to that? “You know well it makes sense. Trump snorted his way through the first two debates.” The drug test business is just Trump's way of saying everybody knows this woman is not healthy and they're doing something to get her vertical for 90 minutes every one of these debates. This woman has seizures, this woman can't get into a van by herself. This woman is not healthy. She's had concussions or coke bottle glasses. It's his way of trying to rile her up. It's his way of trying to impugn her. Hey, they do this kind of stuff all the time and nobody says anything about it other than well as biased media won't examine but when Trump responds in kind, oh this is so horrible. But this is what it looks like. It's what it's always going to look like, and if you don't have the stomach for this then you really may not have the stomach for fighting back against the establishment.
