Biden calls voter a 'lying dog-faced pony soldier' at New Hampshire event

Biden drew criticism Sunday after he called a woman a "lying dog-faced pony soldier" at a campaign event. In an exchange shared on social media, 21-year-old Georgia college student Madison Moore asked him to explain his poor performance in Iowa.

"It's a good question," replied Biden, whose status as national frontrunner for the Democratic nomination was shaken by a damaging fourth-place showing in Iowa's caucuses.

"Have you ever been to a caucus?" he asked the Mercer University student, who nodded.

"No, you haven't," Biden said. "You're a lying, dog-faced pony soldier." 

Moore told The Washington Post it was "totally irrelevant whether I've been to a caucus or not. Joe's been performing incredibly poorly in this race. His inability to answer a simple question from a nobody college student like me only exacerbates that reality."
