This TNR profile isn’t totally a puff piece, but it makes Huckabee seem admirably nuanced. He lacks foreign policy gravitas, but that distinguishes him only from Giuliani and McCain (and maybe Duncan Hunter) among all the aspirants, and he has the advantage of not having had to cast a vote for or against anything the Bush Administration has does anywhere in the world.
I think he has an appeal beyond his "natural" constituency: his language of self-discipline and self-help sounds like it could be deployed to good effect in a conversation with Oprah Winfrey (shudder!), which means that he’s a Republican who could actually contest the female vote with any comer. I leave it to others to tell me whether he’s manly enough to appeal to men.
