Wisconsin Gov. Scott Walker discussed the 2016 presidential election Sunday, saying Republicans need to look beyond the usual candidates if they are to retake the White House.

"People want new, fresh leadership with big, bold ideas and the courage to act on it," Walker (R) said on ABC's "This Week." "If we’re going to take on a name from the past, which is likely to be former secretary of state Hillary Clinton, I think for the party we need a name for the future."

Walker said he likes his chances if he decides to run for the GOP nomination. "After three elections for governor in four years in a state that hasn’t gone Republican since 1984 for president, I wouldn’t bet against me on anything," he said.

As the discussion turned to foreign policy, Walker said the United States should act aggressively to "take the fight to ISIS and any other radical Islamic terrorist in and around the world, because it’s not a matter of if they attack American soil, but when."

"Ultimately, we have to be prepared to put boots on the ground if that’s what it takes," the governor said when asked whether airstrikes are enough to stop the rise of the Islamic extremist groups.

Walker also addressed immigration, saying he does not support amnesty for individuals who have entered the country illegally. "We need to enforce the laws of the United States, and we need to find a way for people to have a legitimate legal immigration system in this country, and that doesn’t mean amnesty."
