Two Words: Chuck Norris
This is clever stuff from the Huckster. He's had a lot of trouble raising money, but is starting to gain ground in recent Iowa polling. I do honestly think he would be the most formidable Republican candidate. His ideas are generally bad (National Sales Tax! Outlaw Abortion!) but his presentation is incredibly disarming. Unlike il Rudy -- who is sufficiently obvious in his megalomaniacal insanity -- and Romney -- who's equally clearly a used-car salesman at heart -- I think Huckabee's calm and earnest manner would probably sell very well in a country suffering from Bush Fatigue.
He comes off like your best friends square dad: kind of a downer stick in the mud, but not in a way that you initially/actively dislike, plus he wrote a book on weight loss. He's the aw-shucks Republican, the only really "feel-good" candidate on right. It would be a challenging contrast to the pragmatic effectiveness of Sen. Clinton, and I daresay he'd out-grin Obama or Edwards. Hopefully the antipathy towards his candidacy from the Money People will nip it in the bud.
