Mitt Romney boosted sales of his book this spring by asking institutions to buy thousands of copies in exchange for his speeches, according to a document obtained by POLITICO. Romney's book tour ran from early March to late May of this year, and took him to book stores, universities, conferences, and private groups around the country. Their giant purchases helped his book, No Apology: The Case for American Greatness, debut on top of the New York Times bestseller list, though with an asterisk indicating bulk purchases.
