One of the most intriguing potential Republican presidential candidates for 2016 is former CEO of Hewlett-Packard Carly Fiorina. The logic of Ms. Fiorina's candidacy is reasonably straightforward. As the only woman in a crowded field of men, and the only candidate with extensive private-sector experience, Ms. Fiorina, who ran unsuccessfully for U.S. Senate in California, can easily stand out from the rest of the field. Additionally, as a woman, and as somebody whose national profile is not centered around far-right opinions on social issues, Ms. Fiorina could be well-positioned to challenge likely Democratic nominee Hillary Clinton in a general election. Ms. Fiorina might be able to be a strong candidate, but her path to the nomination will not be easy. There is little reason to think that Republican women will automatically support her; and while Republicans hate big government, many primary Republican voters are not exactly enamored of big business either.
