you can disguise it in jargon like "pre-existing conditions", but let's be perfectly clear what huck is saying here: he is in favor of letting people die because they cannot afford to pay their medical bills out of pocket.
that's the bottom line. not every pre-existing condition will kill the person that has it, but some will. if you permit insurance companies to discriminate against them that means a certain percentage of americans with curable diseases will die. maybe that scenario reminds huckabee of an already burned down house, but what it reminds me of is negligent homicide.
