Glenn Beck this week unleashed the most toxic word in the conservative lexicon to describe his fellow Fox News co-worker Mike Huckabee. 

It was a description that startled listeners to his radio show who know that, for Beck, it has a near satanic significance. 

In the past Beck has controversially cliamed that progressivism, meaning an individual with activist liberal political outlook, is a "cancer" which must be eliminated in America. 

So when Beck calls Huckabee a progressive it's tantamount to a declaration of war between the two arch conservatives.

Huckabee's sin was his endorsement of First Lady Michelle Obama's anti-obesity campaign. By pointing out that many American parents regularly feed junk food and sugary soda to their kids, Huckabee was in Beck's view attacking the markets and capitalism - a thing that no conservative should ever do.

Huckabee very reasonably explained that Michelle Obama was not trying to tell people what they can or cannot eat - but instead the First Lady was simply addressing the very obvious American problem of childhood obesity by advocating for healthier diets. 

Beck believes Huckabee became a progressive by simply clarifying that fact. So now he's cancer and must be eradicated, presumably.
