I think a lot of us felt let down by Levi’s last dishings on the Wasilla White Trash, although we learned a whole lot about Mama Grifter’s “family values.” Little things like whining all the time about her job, using Bristol as a surrogate (?) mom, using cans of corn as lethal weapons (complete with collateral damage in the form of refrigerator dents.) But we were hoping for so much more.

And at long last, it looks like we might finally get what we wanted. Levi promises to tell us a lot more this time, and I gotta tell you…. I can hardly wait. It won’t change the minds of the fanatical Mama Grifter fan club, since none of them actually have minds to change. But for the rest of us, it might well be some interesting reading –AT LAST!– from someone intimately connected to the tundra tart and her fishpicker posse.

Levi Johnston is promising to set the record straight about the Palin family.

Touchstone Publishing has a fall publication date for Johnston’s book, “Deer in the Headlights: My Life in Sarah Palin’s Crosshairs.”

Johnston fathered a child with Bristol Palin, the daughter of the former Alaska governor, when they were teenagers. The pregnancy was announced days after Palin was selected as the 2008 GOP vice presidential candidate. The couple broke up after the birth of their son, Tripp, and reconciled briefly.

He’s had a contentious relationship with the Palins.

Johnston says the book, first reported by People.com Monday, will “tell the truth” about that relationship, including his “sense of Sarah and my perplexing fall from grace.”

It isn’t perplexing at all, Levi. You were never more than a prop. When you were no longer necessary, you got the heave-ho.

I understand that Mr. Johnston may have been silent up until now because he thought he could trade his silence for more face time with his son. The love of a child is almost one of desperation, and you’ll do a lot of things in order to not be cut off. But I also think that Levi has probably figured out by now that Tripp is also a prop, and it’s a pretty good bet that Mama Grifter and Little BigHair have been using the boy as a punishment tool for Levi (not to mention the things they are probably teaching the child.) As Levi grows up, he probably grows smarter, which (1.) means that he will be able to checkmate the Palins, who cannot get any smarter, and (2.) as he wises up, he will be looking for ways to make sure his kid knows that he has a dad who loves him.

Unfortunately, this kind of a book is probably the only way he can do that.
