Speech at 2015 CPAC conference: on Homeland Security

Ben Carson: Shia-led Iran is more dangerous than ISIL

Gary Johnson: Government transparency on 9/11 secret reports

A: Government should be transparent, and this report is just another example of non-transparency that ultimately ends up being divulged. Look, whatever's out there, get it out there immediately. Get it out there immediately and let us all deal with it.

Mike Pence: The time has come to dramatically increase defense spending

"I believe the time has come to dramatically increase defense spending to confront the unknowable and knowable threats," Pence said. "Without rebuilding our military, no strategy or innovation, no matter how brilliant, will be sufficient to protect the American people and the sovereignty of the US.

Rand Paul: National defense should be unencumbered by nation building

"When I look at government, I think the most important thing we do at the federal level is defend our country, without question," he stressed. "I envision an America with a national defense unparalleled... and unencumbered by nation building."

Sarah Palin: Let veterans apply skills to skip state certification

She noted the lack of services for veterans and said the best way to honor them is by helping them.

She floated a policy idea--using the skills veterans have learned in the military, say computer programming, and sparing them the requirement to get some kind of certification when, in fact, they already have the necessary skills. She discussed making veterans benefits permanent and less subject to the whims of Congress.

Rand Paul: Kids are concerned with privacy & the surveillance state

"Younger voters in particular don't like hypocrisy," Paul continued. "Him saying recently down in Florida that he would still incarcerate people even for medical marijuana, and then it turns out--him basically acknowledging that he'd been using recreational marijuana as a kid. I don't think anybody faults him for youthful indiscretions. But if you look at the people who end up getting caught up in the war on drugs, they're often not elite kids at prep schools. They're poor kids with no school."

Sarah Palin: Dozens of veterans per day commit suicide; VA should help

The former vice presidential candidate also said that veterans weren't receiving the care that they needed from the Veterans Affairs Department and alluded to the scandal over long waiting times for appointments at VA hospitals: "America hands over her sons and her daughters with the promise that they're going to be taken care of," Palin said. "We can't wait for D.C. to fix their bureaucratic blunders. This bureaucracy is killing our vets. They wait for months, they wait for years to get treatment at the VA, and they're losing hope."

Scott Walker: Build up U.S. military to take out ISIS entirely

Scott Walker: Ensure against radical Islamic terrorism on American soil

I know all of you parents [with children in military service] feel the same way: I want to know the commander in chief will do every thing in their power to ensure that the threat from radical Islamic terrorists do not wash up on American soil. We will have someone who leads. And ultimately we'll send a message not only that we will protect American soil but do not take this upon freedom loving people anywhere else in the world. We need a leader with that kind of confidence. I can take on a 100,000 protesters [in union protests in Wisconsin and] I could do the same across the world.
