Sarah Palin's new book may already be a best-seller, but President Barack Obama says he probably won't read it.
The president says he's sure sales of "Going Rogue" will do well without his readership. While he wouldn't say whether he thinks Palin will run for president in 2012, he says she has proved to be a popular figure with a large following in the Republican party.
In an interview promoting her book, Palin rated Obama's performance as president as a 4 out of 10. Obama dismissed the criticism, saying he and the former Republican vice presidential candidate have different political philosophies.
Obama spoke during interviews with CBS News, CNN and Fox News.
