What gives?

In the 20th September New York Times Book Review, the following non-fiction line-up in the Best Sellers list is this:

1) Culture of Corruption, by Michelle Malkin. President Obama and his team as tax cheats, petty crooks, influence peddlers and Wall Street cronies. (Number 1 last week)

6) A Bold Fresh Piece of Humanity by Bill O'Reilly. The Fox News commentator on his upbringing and career. (Number 5 last week)

7) Liberty and Tyranny by Mark Levin. A conservative manifesto from a talk-show host and president of Landmark Legal Foundation. (Number 9 last week)

And in paperbacks, Glenn Beck's 'Common Sense' is number one.

So what gives? I suppose, to be fair, the rants about Bush were pretty common and high up on the best seller list. I'd have to go back and see but not now....
