If you want to know what gives the GOP's economic conservatives (i.e. The Club for Growth) the willies about Huckabee, take a look at his response in yesterday's debate to a question about how he would put his faith into public policy.
THE TWO OVERRIDING PRINCIPLES ARE YOU TREAT OTHERS AS YOU WISH TO BE TREATED. IN HEALTH CARE THAT MEANS WE RECOGNIZE THAT THE PERSON WHO IS SICK SHOULDN'T BE TREATED DIFFERENTLY BECAUSE HEIR [THEY'RE] IN POVERTY THAN A PERSON WHO HAS EXTRAORDINARY WEALTH. THAT WE HAVE SOME SENSE OF BALANCE IN HOW WE APPROACH THAT. THAT'S THE ESSENCE OF WHAT AMERICA IS ABOUT. THE SECOND BASIC PRINCIPLE IS THAT IN AS MUCH AS YOU'VE DONE IT TO THE LEAST OF THESE, MY BRETHREN, YOU'VE DONE IT UNTO ME. AS IT RELATES TO HEALTH, EDUCATION, OR ANY POLICY.
The two principles derive from the Golden Rule ("Do unto others...," from Matthew 7:12) and the injunction to help the poor, from Jesus' account of how the sheep and the goats are to be separated at the Last Judgment, at the end of Matthew 25 ("Then he will answer them, saying, ‘Truly, I say to you, as you did not do it to one of the least of these, you did not do it to me.’ And these will go away into eternal punishment, but the righteous into eternal life.”) Hillarycare, anyone?
