I see James Young broke a story yesterday on Jeff Dion's involvement in the boy scouts, which appears to be against their rules. In addition Dion is making a point not to promote it. Now two other conservative bloggers in Prince William (here and here) have picked up on this story.
Lesson for future candidates: Release everything about yourself. This wouldn't be an issue if Dion addressed it in advance, but instead he has handed his opponents an issue.
