Mitt Romney, the 2012 Republican presidential nominee, refused Sunday to rule out becoming the nominee again this year at a brokered convention, though he insisted he couldn’t imagine that happening. “I don’t think anyone in our party should say, ‘Oh no, even if the people of the party wanted me to be president, I would say no to it.’ No one is going to say that,” Mr. Romney said on NBC’s “Meet the Press.”
