As I understand it, her historical campaign style has actually been to deliberately emphasize wedge issues (for example bringing religion, abortion, and gun rights into a Mayoral race). It's not obvious to me whether she even has positions on some of the other things (for instance, I suspect she's playing catch-up on most foriegn policy issues). I agree with you in spirit that we should be comprehensive in our coverage, but we also have to keep in mind that some topics, like pro-life positions, gun rights, and oil exploration, are more developed in part because those are things Palin herself has chosen to emphasize during her career.
