JEFF ZELENY, CNN CHIEF WASHINGTON CORRESPONDENT: Well, I think Carly Fiorina is trying to step into Hillary Clinton's spotlight. And why not? There is a captive audience here. Carly Fiorina had probably the largest gathering of her young campaign. She was taking advantage of all the reporters waiting for Hillary Clinton to show up.
She really has been going across country like most Republicans trying to distinguish herself by attacking Hillary Clinton.
That is really what republicans are trying to do, elevate themselves in their own very crowded field. But particularly for Carly Fiorina, she is trying to take gender off the table and said if she was at a debate with Hillary Clinton at a debate site, she said that Hillary Clinton will not be the first woman contestant. She is campaigning here in South Carolina and across the country.
