now. "Your voice, your vote" with just 19 days to go. And things are heating up even more after that ferocious second debate. One of mitt romney's sons letting loose on how he really feels about president obama overnight. And david muir is here with the details. Reporter: The campaign telling me this morning that romney's son, tagg, was joking about how frustrating the process can be for the family, when he told a radio host, that while watching that debate, he wanted to go down and take a swing at the president. Overnight, a new sign of how contentious this race has become. Tagg romney, telling a radio host, watching that debate, wanted to make him take a swing at the president. What is it like for you, to hear the president of the united states, call your dad a liar? Jump out of your seat. And you want to rush down to the debate stage and take a swing at him. You can't do that because -- well, first, there's a lot of secret service between you and him. And because it's also the nature of the process. Reporter: It comes after the town hall debate, with the president and mitt romney just feet apart, talking over each other. The president never called romney a, quote, liar. But overnight, the president did take aim at something mitt romney said at the debate. Talking about hiring women as governor. I went to women's groups. And they brought us binders full of women. We don't have to order up some binders to find qualified, talented, driven, young women. Reporter: The romney campaign arguing it's a distraction from the real issue, most important to women, the economy. Arguing 3.6 million more women in poverty. This president has failed america's women. Reporter: Overnight, the late night comics with a binder full of jokes. He had binders full of women. His policy towards women is clear. We have to alphabetize them. Reporter: On the binder blunder, governor romney tweeting out, I understand the challenges that women face. Tweeting a link to testimonials to women who worked with h as governor. Both sides with an intense focus on women that could be the factor come election day. Let's talk about that.
