Update: Wow, Limbaugh digs himself much deeper. He claims that he was referring to people who claim to be soldiers but in fact aren't. And then he gives an example: John Murtha.
That would be the same Murtha who earned the Bronze Star with Valor device, two Purple Hearts, the Vietnamese Cross of Gallantry, and the Navy Distinguished Service Medal.
Got that? "Phony soldiers" was a literal reference to those who've lied about serving, a list which Limbaugh believes should include decorated war hero Jack Murtha.
