Many volunteers heed Huckabee's call:

The Values Voter barnstorm will be led by Pastor Rick Scarborough, an early Huckabee endorser. Participants include R. Randolph "Randy" Brinson, an iconoclastic social conservative doctor from Alabama who possesses a huge list of Iowa pastors and Christian conservatives. He's also the head of ReedemTheVote, which was active in 2004 and 2006 as a voter registration vehicle for young evangelicals.

The Barnstormers don't have to reveal their funding sources provided they don't directly provide aid to a candidate. But it's hard to see how any candidate but Mike Huckabee will find comfort from this tour.
