Rush Limbaugh is a shock jock. He gets good ratings by being controversial (by, surprise-surprise, saying controversial things). Regardless of merit, he is also influential (he is the real life jmfcst, the leader of the jmfcsts). With regards to politics, the signal is clear: Romney is stepping on egg shells with Limbaugh because he respects Limbaugh and does not want to incur his wrath. Limbaugh could appreciate this, and may possibly consider calling the GOP war over if Romney is successful on Super Tuesday.
All that tells me is that when it comes to Rush Limbaugh, Romney is, first and foremost, SPINELESS. A "valueless cipher"(Lief), indeed
