Carly Fiorina has conservative Republican leanings, though she has shown an unusual amount of sympathy for the pro-choice movement. She actively supported John McCain and Mitt Romney for president in 2008 and 2012, respectively. She was the Republican candidate for the United States Senate from California in the election of 2010 but lost to incumbent Democratic Senator Barbara Boxer. On May 4, 2015, Fiorina formally launched a campaign for the Republican nomination for president of the United States in the 2016 election.
On February 20, 2009, Fiorina was diagnosed with breast cancer. She underwent surgery at Stanford Hospital on March 2, 2009, followed by chemotherapy, which caused her to lose her hair, and radiation therapy. She has been given an excellent prognosis for a full recovery.
