Ann Kirkpatrick in 2016 AZ Senate race

On Energy & Oil: Some government action for climate change

Kirkpatrick: Yes

McCain: Clear acknowledgement in the past, but more recently has questioned. Also voted against amendment stating that human activity causes climate change.

Q: On Climate Change: Should government limit the levels of greenhouse gasses in the atmosphere?

Kirkpatrick: Mixed. Supported some, but opposed Obama's Clean Power Plan and sought to delay new ozone standards. Acknowledges need to fight climate change and reduce carbon footprint, but environmental record mixed--wary of efforts she says could harm local economies or keep us dependent on foreign oil.

McCain: Previously yes, currently no. Voted to overturn Obama's Clean Power Plan, delay ozone standard, and prohibit carbon tax.

On Government Reform: Joined lawsuit challenging AZ voting restrictions

Kirkpatrick: No. Joined lawsuit challenging AZ voting laws [which reduced the number of polling places in Maricopa County from 403 in 2008, to 211 in 2012, to 60 in 2016].

McCain: Position unclear. No visible stand found for or against increased requirements.

On Government Reform: Overturn Citizens United with constitutional amendment

Kirkpatrick: No. Supports Constitutional amendment to overturn.

McCain: No. "Worst decision ever." But voted against Constitutional amendment to overturn.

Q: Do you support the DISCLOSE Act, which requires key funders of political ads to put their names on those ads?

Kirkpatrick: Yes

McCain: No. Says objection is about how Act is written.

On Homeland Security: Supports Iranian nuclear deal & Congressional debate on war

Kirkpatrick: Yes

McCain: No

Q: On Iraq: Should the US recommit significant additional ground troops to Iraq to combat the success of ISIS?

Kirkpatrick: Wants to do more, but wants Congressional debate before any decision to send more troops.

McCain: Yes. Wants to send in significantly more troops. Criticizes Obama's "grudging incrementalism."

On Drugs: Protect state marijuana laws from federal interference

Democratic opponent Ann Kirkpatrick, on the other hand, voted on at least two occasions for amendments to protect state medical marijuana laws from federal interference. She also voted for a broader amendment to prevent the Department of Justice from interfering with any state marijuana laws, including ones that legalize recreational use. However, she also sponsored two versions of legislation to prevent people from using or withdrawing food stamp benefits at marijuana dispensaries.

On Principles & Values: Arizona is changing; voters are ready for a choice

But it's the boots she bought with her waitressing tips that are likely to take center stage in the race. Those same boots became a symbol in her last campaign as Republicans sought to portray her as some sort of high-heeled Washington liberal.

Kirkpatrick, 65, was careful not to blast the 78-year-old McCain, a former prisoner of war in Vietnam, who was first elected to the House in 1982 and to the U.S. Senate four years later. Instead, she said, it's about giving voters what she thinks they want now. "The state's changing," she said. "I hear from Arizona voters who are ready for a choice in the next election.'
