It's the latest round in the grudge match between Huckabee allies and the Club, which dates back to 2006
Democrats are also competing to hold the 4th District, but they face an uphill climb. Attorney Q. Byrum Hurst entered the race late to save his party from two unenergetic, unviable candidates, but he had faced a torrent of bad press about personal tax issues since then.
Democrats are also vying for the nomination to take on Republican Rep. Rick Crawford
in Arkansas's 1st District, but the race has been slow to take shape. State Rep. Clark Hall
is favored by national Democrats and seen as one of the party's best hopes to win a Southern seat this cycle, but he has two primary opponents to get past first: prosecutor Scott Ellington
and professor Gary Latanich
. Hall is the only one of those three to hit television in the primary.
