Ya. Rush, Levin,all Conservative Talk show hosts, Palin, Walker, all Conservative Politicians, are all ABO.
You're not surprised by this, are you? Conservative politicians can't jeopardize their standing in the Republican Party if they might harbor long-term political ambitions. Conservative media people have a stake in not offending the Republican Party. If you look at the earlier comments made by most of these people about Romney before he became the nominee and it is clear that their support of him now is nothing more than a tepid marriage of accomodation.
I can understand why they "support" Romney given their vested interest in aligning themselves with the Republican Party. What I can't understand is why conservatives who have no such vested interests can support someone who should be anathema to conservatives.
