Until Levi's next interview, and then the one after that... It's not like the media's going to stop giving these people airtime.
How long before some idiot gives him a book deal?
That's certainly in the realm of possibility. Palin only increases the books value every time she responds to the kid.
The next round of headlines will be...
SARAH PALIN ATTACKS GRANDCHILD'S FATHER.
That headline doesn't exist and the impetus to get Levi's reaction doesn't exist if Palin issues a "No Comment" statement. It's called managing the news cycle in the PR biz.
