A new book about Sarah Palin makes shocking allegations that could jeopardize the Tea Party politician's political aspirations.

Joe McGinniss' The Rogue: Searching for the Real Sarah Palin, alleges that the former Alaska governor and vice presidential candidate had an affair with then-University of Michigan star basketball player Glen Rice,in the 1980s, snorted cocaine, had an affair with her husband's business partner for six months and smoked pot in college with a professor, according to a preview in the National Enquirer.

The book is to be published in the U.S. next Tuesday by Crown, a division of Random House.

The Enquirer reported that McGinniss claims that Sarah Heath had a one-night-stand with Rice in the 1980s, before she married Todd Palin. Rice went on to have a very successful NBA career and was a three-timer All-Star.

In the book, McGinniss quotes Rice as confirming the one-night stand, stated the Enquirer report.

The book also claims that Palin was seen snorting cocaine off the top of a 55-gallon drum while snowmobiling with her husband and friends and that she smoked marijuana with a professor while at Mat-Su College in Alaska.

The book apparently quotes a Palin family friend as alleging that Palin's husband, Todd, also used cocaine and that he was on the end of the straw plenty.

McGinniss' biography also claims that Palin had a six-month affair with her husband's business partner, Brad Hanson, which led to Todd ending the business deal when he learnt of the affair.

According to http://thecaucus.blogs.nytimes.com, many episodes cited in the book relied on unnamed sources or second or third-hand accounts.

McGinniss, who has written many books over four decades, including The Selling of the President and Fatal Vision, moved next door to Palin's home in Wasilla, Alaska, while writing the book. Palin warned him to not to spy on her family, saying she suspected he was trying to look in her daughter's window from his property, reports the guardian.co.uk.
