Republican presidential candidate Carly Fiorina was the consensus winner of the second GOP debate last Wednesday.

Now, America wants to know who she is, how she would lead and how she acts outside the office and off the debate stage.

Fox News' John Roberts got exclusive, behind-the-scenes access to the Fiorina campaign, getting up close and personal with the former Hewlett-Packard CEO on the road.

Fiorina opened up about her meteoric rise up the polls, her failed Senate bid, her battle with breast cancer and the tragic death of her stepdaughter.

Lori Ann Fiorina died in 2009 at age 34 after a long struggle with drug and alcohol addiction, as well as a bout with bulimia. 

Fiorina mentioned the tragedy in last week's debate during a discussion about marijuana legalization, when Jeb Bush casually acknowledged he had smoked pot 40 years ago. 

Fiorina answered that, "My husband, Frank, and I buried a child to drug addiction. The pot today is very different than pot Jeb just admitted to smoking 40 years ago.”

In an emotional moment, Fiorina told Roberts about a poem that her stepdaughter wrote to her. 

"It says, basically, I don't tell you enough that I love you. And ... when you lose someone, you realize we never say it enough," said Fiorina.
