Candidates and spouses?

I was really young, but it seems to me that when Geraldine Ferraro ran for vice president, everything her husband had ever done was out in the open press. When Bill Clinton ran for president, we heard all about Hillary’s buisness, being the first “working” first lady. We even heard quite a bit about the accomplishments of Lynn Cheney. How come we are not hearing anything about Palin’s husband? If you search the internet you can find plenty of stuff about his Independant party affiliation, but nothing in the mainstream media about who he is, his background, his education or his politics. Why is that? Is it just so inflamatory that they are afraid to tell us or is there just nothing there to tell?
