The wife John McCain callously left behind

McCain likes to illustrate his moral fibre by referring to his five years as a prisoner-of-war in Vietnam. And to demonstrate his commitment to family values, the 71-year-old former US Navy pilot pays warm tribute to his beautiful blonde wife, Cindy, with whom he has four children.

But there is another Mrs McCain who casts a ghostly shadow over the Senator's presidential campaign. She is seldom seen and rarely written about, despite being mother to McCain's three eldest children.

And yet, had events turned out differently, it would be she, rather than Cindy, who would be vying to be First Lady. She is McCain's first wife, Carol, who was a famous beauty and a successful swimwear model when they married in 1965.

She was the woman McCain dreamed of during his long incarceration and torture in Vietnam's infamous 'Hanoi Hilton' prison and the woman who faithfully stayed at home looking after the children and waiting anxiously for news.
