"I could stand in the middle of Fifth Avenue and shoot somebody, okay, and I wouldn't lose any voters, okay?" Trump said at a rally in Sioux Center, Iowa as the audience laughed. "It's, like, incredible."
Trump has previously boasted about the devotion of his fans, but the new comment is the most extreme example of such a remark.
A recent NBC News/Survey Monkey poll suggested that Trump supporters, once decided, are likely to stay with him. About half of respondents backing the real estate mogul said they were "absolutely certain" that they will vote for Trump.
