Sarah Palin has been offered $1million if she passes a lie detector test over claims made a Joe McGinniss’s book about her.

In Joe McGinniss’s book Sarah Palin is accused of cheating on her husband Todd Palin, with his ex-business partner and using drugs.

The former Alaska Governor has vehemently denied everything.

The adult website AshleyMadison.com has offered Todd and Sarah Palin $1 million to prove their innocence.

Todd Palin, Sarah Palin’s husband has said of the book, “The Rogue: Searching for the Real Sarah Palin”:

“His book is full of disgusting lies, innuendo and smears.”

Todd and Sarah Palin have been offered $1 million if they pass lie detector test over Joe McGinniss' book claims.

The letter to Todd and Sarah Palin from AshleyMadison.com said:

“We will hire a certified polygraph examiner to administer a lie detector test to both yourself and Todd.

“He will be restricted to asking you questions solely related to the allegations.”

“If both of you complete and pass the polygraph test, Ashleymadison.com will issue you a check in The amount of $1,000,000.”

The $1 million offer comes just days after the National Enquirer claimed that friends close to Sarah Palin and her husband Todd say he is “fed up” with the constant scandals that have plagued their marriage ever since she ran for vice president and is ready to file for a divorce.

It has also been alleged that Sarah Palin advisers have told her to kiss goodbye to the White House fearing a bid would be “political suicide”.

The explosive book is said to have put the final nail in the coffin of Sarah Palin marriage, after her brother Chuckie was quoted saying she and Todd's marriage was over

In Joe McGinniss’ book, Sarah Palin, 47, is accused of having a night of passion with basketball star Glen Rice and snorting cocaine.

Another source close to the former vice presidential candidate said:

“Sarah Palin has been destroyed by Joe McGinniss’ no-holds-barred biography. It exposed all her lies, cover-ups and secrets.

“As a result she has been told by her advisers that it would be political suicide to announce a White House candidacy.

“The press and her opponents would have a field day digging into the dirty details of her background.”

The explosive book is said to have put the final nail in the coffin of her marriage, after Sarah Palin’s brother Chuckie was quoted saying his sister and Todd’s marriage was over.

Sarah Palin is currently travelling the country and is still deciding whether or not she will run for presidential race in 2012.
