Huckabee isn’t just the anti-Fred, he’s the anti-conservative.
With the exception of a major melt down, I don't see the voters that switched from Fred to Huck (remember in the beginning his surge coincided with Freds decline) switching back to him without him making some major change in his campaign. I don't think Fred can sit around and hope that people realize Hucks nanny state tendencies.
I could be very wrong, but when I saw Huck the other night at the debate, I said WOW, and this is coming from someone that knows his shortcomings, and has no plans to vote for him in the primary. I still say likability trumps almost everything, and Huckabee has that, Fred just doesn't.
