Cancer-ridden Elizabeth Edwards ripped open her shirt screaming "Look at me!" at a terrified John Edwards after his affair with Rielle Hunter was first exposed by The ENQUIRER, a new book reveals.

Change Game an inside account of the 2008 Presidential Race by John Heilman and Mark Halperin reveals shocking new details about the John Edwards cheating scandal.

In the book, Edwards is described as an out-of-control narcissistic who became an egomaniac after meeting future mistress Rielle Hunter.  His affair with Hunter, who told people she was a "witch", was an open secret among his chief advisers — three who quit early in the campaign.

John Edwards is described as delusional while the public image of "saintly Elisabeth’s public persona" is shattered. 

Openly battling with John in front of aides, she belittled her "intellectually inferior" hubby in front of  campaign workers.

Insiders describe her  as "an abusive, intrusive, paranoid condescending crazy woman," according to the book.

When The ENQUIRER first revealed the affair,  John and Elizabeth fought violently in the parking lot of an airport terminal.

"Elizabeth was sobbing, out of control, incoherent.  As their aides tried to avert their eyes, she tore off her blouse exposing herself. ‘Look at ME!’ she wailed at John and then staggered, nearly falling to the ground," the authors recount.

In the wake of Edwards dismissal of The ENQUIRER’s investigation as "tabloid trash" it was only after The ENQUIRER’s world exclusive  "spy photo" appeared in print and online of the disgraced candidate holding his love child by Hunter that Edwards admitted the affair,  denying paternity,  on national TV.

"Confronted then with the ENQUIRER photo of her husband cuddling Hunter’s baby, she insisted to (an aide) that she still believed he was not the father.

‘I have to believe it,’ Elizabeth said.

‘Because if I don’t, it means I’m married to a monster.’"

With former loyalist and pretend daddy Andrew Young‘s insider tell-all of the affair and the cover-up to be published next month AND the ongoing Federal grand jury investigation into misuse of political campaign funds to engineer payoffs to his mistress, for John Edwards the WORST is YET to come.
