Careful about generalization
First it is important to distinguish between Mike Huckabee's supporters and Mike Huckabee. I truly believe that Mike Huckabee is a tool of the establishment and was used by them to ensure John McCain's nomination. (He was the ideal Romney-killer, played the "Mormon card" to perfection, and will probably be rewarded with the vice presidential nomination.)
That being said, however, I believe that many if not most of his supporters have great potential for becoming "Ron Paul Republicans".
Most people do not appreciate the fact that the supporters of Huckabee were attracted by a few very simple things; his conservative stance on social issues, fundamental Christian credentials, and his charisma/ready humor.
Frankly, all of these things are fairly irrelevant one comes to the liberty movement. Otherwise, most of these people are ripe for RP's message, and this has been reflected in the response we have had working as delegates in Iowa. It is a shame that our campaign was not able to get to these voters first, but you can blame the well-orchestrated MSM campaign prior to the Iowa caucuses for that.
