You're not liable to find a better example of a complete asshole in life, but the following link from Snopes shows just how devoid of any common decency he was:
Iowa’s Cedar Gazette reported in 1990 that Limbaugh’s “AIDS Update,” a recurring segment in which he made jokes about a disease that had killed more than 100,000 people in the United States the previous decade, started by playing songs such as “Back in the Saddle Again,” “Kiss Him Goodbye,” “I Know I’ll Never Love This Way Again,” and “Looking for Love in All the Wrong Places.”
Granted, he expresses regret about that bit, but as the article makes clear it didn't stop him from being a raging homophobe elsewhere. And he also bitched about "harassment", which is a self-serving way of characterizing the criticism he so richly deserved.
I'm sure someone will miss him outside of his immediate family. I'm just not sure why.
