Republican presidential front-runner Donald Trump listed a few of his fellow 2016 rivals as possible running mates in an interview published Monday. Speaking to columnist Kirsten Powers, Trump spoke favorably about Sen. Marco Rubio (R-Fla.) who he famously feuded with before defeating him in his home state.... “There are people I have in mind in terms of vice president. I just haven’t told anybody names,” he said. “[I] do like Marco. I do like (John) Kasich. … I like (Scott) Walker actually in a lot of ways. I hit him very hard. … But I’ve always liked him.”
