OXON HILL, Md. (AP) — Wisconsin Gov. Scott Walker says his experience taking on protesters in his state helped prepare him to take on terrorists across the world. The likely Republican presidential contender on Thursday appeared at the Conservative Political Action Conference — known as CPAC — in suburban Washington. Asked how he would handle the Islamic State group, Walker said he’s been concerned about the terrorist group for years — at home and abroad. He told the conservative audience that if he can take on 100,000 protesters, he can do the same across the world. The Wisconsin governor has faced particularly aggressive protests over his budget policies in the four years since he took office. He’s gearing up for a 2016 presidential contest in which foreign policy figures to play prominently.
