Query: Terrible

Biographer clearly took a biased approach in recounting thelife of Ronald Reagan, reducing the likelyhood of telling the fullstory. The prologue reveals all when Morris refers to Reagan as an Iguana and ascribes Reagan motivations to 1950s movie. Every biographer has opinions and biases, of this no one doubts, but to blatantly pass them unfiltered to the reader devalues this work to historical fiction. If anyone wants my copy of the hardback, you'll find it at the dump.
