Query: biased

I commented on the "Adams" book, by McCullough as being too biased to be good history and should be taken with a grain of salt. I am becoming bitterly disappointed in McCullough, as a historian. I am now reading "Truman", by Mc, and find the same thing! McCullough, a liberal, falls in love with his liberal subjects. This makes for very, very bad history. I have a recurrent mental image of Adams and Truman walking hand-in-hand, McCullough in the lead, over the waters into a golden sunset. I am only to page 300, I will try to add another entry upon completion I think this book is BIASED,BIASED,BIASED.Very bad history.
