(CNN) -- When did conservatives become prisoners to idiotic vulgarity? I ask that question as someone who self-defines as conservative and who is sick and tired of being embarrassed by Ted Nugent. 

Last month the aged rocker called President Barack Obama a "subhuman mongrel" in an interview with Guns.com. That was bad enough, but what was just as shocking was the willingness of Texas GOP gubernatorial nominee Greg Abbott to keep him aboard his campaign. 

Rick Perry and Ted Cruz also failed to rule out appearing with him. Only Rand Paul took to Twitter to demand an apology, which Nugent eventually gave. He downgraded Obama to a "liar," which is, at least, a more colorblind insult. 

There is a view that Nugent simply "speaks his mind," and, yes, he has every constitutionally guaranteed right to do so. Maybe what he says appeals to some people, those for whom good manners are a bourgeois affectation and correct spelling the preserve of Harvard pointy-heads. 

Nugent insists comments not racist, promises to stop 'calling people names' 

Either way, what is disturbing is that some serious Republican politicians think that he matters and are happy to count him among their endorsements -- as though selling records and getting angry make him a spokesman for the masses. Animal from the Muppets also speaks his mind, but we've yet to see him headlining a rally for Chris Christie. 

This isn't what conservatism is supposed to be about. Conservatism is the rejection of ideology in favor of common sense and anger in favor of cool rationalism. 
Where did he express that?
