There's the video link to the interview with Sean Hannity where he discusses it. He says "So I shamelessly say no, I want him to fail if his agenda is a far left collectivism (some people say socialism)... as a conservative heart-felt, deeply... why would I want socialism to succeed?" I think there is your context of what he was saying.
(BTW, I don't read Limbaugh's site, it was linked on Drudge.)
