Carly Fiorina Republican Former business executive

The former chief executive of Hewlett-Packard, Mrs. Fiorina is the only woman in the Republican field. Her campaign is built around her story of success in the private sector, where she rose from secretary to leader of a major technology company. She is hoping for a better result than in 2010, when she unsuccessfully ran for the United States Senate in California.

  • “It’s ideology, not common sense, that causes the left wing, every time, in a knee-jerk reaction, to say the answer here is more laws, when we’re not enforcing the laws we have.”

  • “We cannot permit refugees to come into this country unless we can vet them — and we cannot.”

  • “This is a tricky maneuver, it’s a dangerous maneuver, but it’s a maneuver that we must undertake.”

    Mrs. Fiorina called for a no-fly zone to protect rebel forces that are opposing President Bashar al-Assad. She said that such a move would show the Russians “that they do not get to move into the Middle East and become the dominant outside power.”

  • China has tried “to engineer a soft landing for their economy, and it appears they have not succeeded in doing so.”

    Seeking to buff her foreign policy credentials, the former technology executive has used the faltering Chinese economy to pivot to a discussion about that nation's rising military aggression.

  • “If you have come here illegally and stayed here illegally, then you don't get a pass to citizenship.”

    Mrs. Fiorina has said she is open to legal status for those here illegally, and to allowing children of illegal immigrants to gain citizenship.

  • “We ask every agency to justify every single program every year.”

    Mrs. Fiorina favors "zero-based" budgeting instead of formulas based on agencies' previous-year spending, as a way to rein in costs.

  • “The scientists that tell us that climate change is real and caused by man-made activity also tell us that a single nation acting alone can make no difference at all.”

    Unlike many Republican candidates, Mrs. Fiorina acknowledges that climate change exists. But she typically argues that potential solutions are either too costly or unfeasible.

  • “The alternative is to allow states to manage high-risk pools for those who really need help.”

    She favors replacing the Affordable Care Act with federally subsidized, state-run programs restricted to the poorest and sickest patients.

  • Her 2010 Senate campaign said she “supports the death penalty for our nation’s worst murderers.”

    Mrs. Fiorina remains supportive of the death penalty, according to a spokeswoman for her presidential campaign.
