Wisconsin Gov. Scott Walker, a possible Republican presidential candidate, on Sunday doubled down on the notion that his union busting experience was what was needed to defeat the terrorist group ISIS.

While speaking at the Conservative Political Action Conference (CPAC) last week, Walker had said that dealing with protesters who opposed his so-called right-to-work legislation was like fighting ISIS.

“If I can take on 100,000 protesters, I can do the same across the world,” Walker insisted.

In an interview on Fox News Sunday, host Chris Wallace observed that part of Walker's appeal to conservative voters was that he took rights away from the public worker unions.

"But this week you seemed to compare that to taking on ISIS," Wallace noted. "Governor, isn't there a big difference between protesters and terrorists?"

Walker agreed, and insisted that he had "made that clear."

"And I want to make it clear right now," he continued. "I'm not comparing those two entities. What I meant was, it was about leadership."

"The leadership we provided under extremely difficult circumstances, arguably the most difficult of any governor in the country, maybe in recent times," Walker opined. "To me, I apply that to say, if I were to run and if I were to win and be commander-in-chief, I believe that kind of leadership is what's necessary to take on radical Islamic terrorism."
