Am still disgusted that Repubs are compelled to apologise for 'ugly truths spoken'; while the Left refuses to apologise for their 'just plain ugly' lies.It is infuriating, the hypocrosy of the left, however we do strive to live in a civil society and we must therefore act accordingly. By apologising, Rush showed that he is still above the fray, imho.
Think he could have apologised but with a bit more finesse i.e. for his 'choice' of words; while not disarming his original and honest intent and point. But; yes; we cannot say he did not at least 'go there' and eat humble pie for the sake of 'good' - or at least, the 'good' per his Advertisers. (That helped!)
OTOH; like Andrew Breitbart's MO per apologies 'for what'; was his reply to Left.
