Kudos to Dave Catanese for his video interview with Kenny Hulshof [1].  Catanese sticks by his guns and refuses to let Hulshof off the hook by forcing him to answer for his history of supporting Congressional earmarks.  Here's Hulshof explaining carefully his nuanced position on the topic:

"In every instance, my principle is that the person that wants to cut this proposal has to make the case to me that it is worthwhile to cut and then whoever proposes the earmark has to defend that earmark."

Watch the video yourself (it's the first of the three clips) if you don't believe it.  Hulshof actually admits that his presumption is that any earmark included in a piece of appropriation legislation should get the benefit of the doubt, and that opponents of a particular earmark have to prove to him that it shouldn't be included.

Hulshof's is a truly frightening position: he votes for wasteful spending unless someone can convince him not to.
