Please read all the way to the bottom for the updates on the mysterious author of the book.
Well, that was quick.
"New Hampshire-based political analyst J. A. McClure" is offering a 100-page book about Gov. Tim Pawlenty on Amazon.com. The booklet, portions of which are available for free on Amazon, on the "The Sam's Club Republican" appears to be largely an able, but non-newsy, clip job about the governor. (Meanwhile, Pawlenty seems to have mostly dropped the "Sam's Club" references from his stump speeches.)
Update:
A google search for McClure draws a blank and his name doesn't seem to pop up in the New Hampshire political analyst world.
"I've never heard of him and it is a very small state," said New Hampshire political analyst and journalist James Pindell, who is eminently google-able.
