The guy is basically the same as Romney and Rudy but with a pretend conservative face. The establishment realised that Rudy, Rommel and McCain are unpopular and not conservative so they needed another candidate... cue press attention and even an interview with slick willy clinton saying how well Huck's doing. Huckabee's an establishment candidate, as shown by hiw willingness to argue about the "honor" (hmmmm?) of fighting aggressive wars.
Be nice to the people who support Huckabee. They will usually just be going off soundbites - conservative sounding ones - so present them with the record and contrast with RP's record and we should be able to win some converts.
