Carly Fiorina battled boardroom enemies at Hewlett-Packard (and was fired). She mounted a campaign to unseat U.S. Sen. Barbara Boxer (and lost). She fought cancer (and won). As the only woman Republican presidential candidate, she took on six rivals in a "junior" debate last month (and won).
So now, after convincing CNN to bend the rules and allow her to debate with the 10 GOP front-runners on Wednesday, the real question is, can she handle the biggest boardroom bully of all, Donald Trump?
The answer could mean the difference between whether Fiorina -- the closest thing to a California candidate -- sizzles or fizzles.
