I like both Huckabee and Romney. But I wouldn't vote for Huckabee, and I'm unsure of Romney. On Charlie Rose on PBS, I saw N Y Times writer David Brooks give a nice perspective on all the candidates, post-Iowa.
Regarding a debate exchange, he related Huckabee said to Romney: "I look like the guy people work with, you look like the guy who lays them off."

I thought that was a terrific line.

Despite his flaws, Huckabee definitely appeals to the blue-collar lower-middle-class working man, and that line contrasted well himself with the (perceived) relatively distant and well-monied Romney.

It was pointed out that some of the heat from the other candidates, such as McCain and Huckabee, might stem from their resentment that Romney has a well-funded campaign (partly from his own personal fortune), while they have very limited campaign war-chests and have to struggle for every dollar.
