Even if we concede that Limbaugh was over the top (again, ala "South Park" and Reeve), Fox was the one who chose to use his illness to score political points.
Clearly, Fox wanted people to feel some level of sympathy for him personally, and to vote based on that emotional response.
That's his right. However, as Lauer and Estritch noted, by doing so he opened his illness up for discussion and, therefore, criticism.
As someone who's been in the public eye for over 20 years, surely Fox is not so naive as to think his entry into partisan politics was immune to comment.
