Hunter defends earmarks. However, he also makes all of his earmarks public knowledge, unlike the rest of the Congresscritter who keep them secret, so the public can decide if the earmarks are pork or properly-directed spending (he has pushed, for example, for better IED counterefforts, but has also pushed for defense contracts for companies in his district - but at least you know what he has put in for).
Well sunshine is always a plus, but earmarks are evil, since they are not subject to a vote. Hunter is suspect on economic issues, in my book.
