(you posted the inflammatory accusation. Back it up with solid facts. I've been listening to Rush as long as anyone and until you back up your words I will consider you a liar and hypocrite).
It’s my opinion based on circumstantial evidence.
1. During republican primary elections, Limbaugh consistently pushes the establishment candidate while talking down the most conservative one. In 2008 he talked down Thompson while pushing Romney. In 2012 he spoke against Gingrich and Santorum respectively, but only at times when each of them could have made strategic gains.
2. Limbaugh was consistently anti-Trump during the primaries and the general. I don’t care if he’s good at nuance, in the end his inclination was always anti-Trump. What Limbaugh is good at (and I don’t consider this a mark of intelligence, only a mark of deceptiveness) is to say just enough to make it appear that he’s in favor of something conservative or pro-American, but pulling back enough and going in the other direction enough that when it could make a difference, his commentary subtly supports the deep state narrative. No different from the Medveds and the Ingrahams.
3. Limbaugh made his money, his fame and his career on the deep state system. As part of the system. Not as an agent opposing it. In my opinion, there’s no way he could be anything but deep state.
