She's trailing Greg Abbott in the polls. She has a brand-new memoir, called "Forgetting to be afraid." In which she reveals painful details about her personal life. When people hear the name Wendy Davis, they think about you and your pink running shoes. Members, I'm rising on the floor today -- On the floor of the Texas senate for hours. For me it was very important to give voice to the women and men that I stood for that day. And of course, I couldn't help but reflect upon my own journey. Reporter: A journey Wendy Davis, a mother of two daughters, shares with the public with her new memoir. In it, Davis reveals for the first time she made the decision to terminate two pregnancies in the 199 0s. The first in 1994 after tests showed the fetus was developing outside the uterus, making it unviable. For me, it was a tremendous loss of a much-wanted pregnancy. Reporter: Two years later, Davis and her then second husband, Jeff Davis, were pregnant again with a daughter they had already named. But during a routine exam, the doctor detected a problem. Our baby had a severe brain abnormality. If she did survive to term, she likely would not survive delivery. If she did survive delivery, she likely would be in a vegetative state. We knew that the most loving thing that we could do for our daughter was to say good-bye. And, like so many other families, across this country, we made that difficult decision with as much love for our daughter as can be imagined. Her name was Tate Elyse Davis. And we loved her as we love our living daughters, drew, and amber. And she forms, of course, a very important part of my life. Can you understand that there will be some that will say, they would have taken a different route? This was how my family confronted this tragic experience. I respect so much that people make their own decisions. That decision is the one that is right for them. Reporter: A Harvard law school graduate, Davis was raised by a single mother who left school after the ninth grade. Davis said her mother struggled. In her memoir, she recounts a dark day. My mother was in her 20s. She had three children, ages about 5 to 1. And she experienced tremendous depression after I was born. My parents separated not long after I was born. My father remarried. And my mother was left in a strange place, she was alone. She almost took her life and ours. She put us into the back of the car. She couldn't imagine leaving the world and leaving us behind. She had intended to start the car in the garage. And an angel came into our lives that day. A neighbor who had never come to our home before rang the bell. And he sat in the living room. He held my mother's hand. He talked to her for quite a long time. And by the time he left, she was through it. And she came and collected us from the car. And put one foot in front of the other. And, pushed on. For all of us. And did a beautiful job of it. Reporter: Davis credits her mother's life experience for giving her strength to persevere when she faced her own challenges of being a single working mother. You know that there will be criticism as to the timing. When the book comes out, it will be less than 60 days from the election. People will question the timing. Are you trying to pull at the heart strings of the voters that you're trying to win votes? With sympathy? I wanted to share a book about my life. How I came to be who I am. I wanted people to feel like they're not alone. The struggle of being a single mom. The struggle after my parents divorced. And that I came through it. Through my faith in god. I came through it because of my education. And I wanted to be very honest in my story. And not leave pieces aside. I wanted people to understand. And there is nothing left aside in "Forgetting to be afraid." It's available tomorrow.
