It's really good - Limbaugh manages to find incidents from the last 2 years that even political junkies like myself have forgotten.
Obama contrasts what he believes Republicans to be with Democrats, whom he flatters by stating that they think for themselves. At least, when they agree with him."Republicans - they're another story altogether. They just kind of do what they're told."
I highly recommend the book. David Limbaugh's website is here. David is the lawyer brother of Rush. Similar politics, very dissimilar style.
BTW, the Kindle edition is a real steal - about 1/3 the price of the hardcover.
