Former Vice President Joe Biden appeared to come unglued during a campaign event in New Hampshire yesterday, calling one voter a “lying, dog-faced pony soldier.”

A 21 year-old woman named Madison Moore, who is a student at Mercer University in Georgia, got up during the event to ask Biden how he plans to stay competitive in the 2020 presidential race.

“It’s a good question,” Biden replied, according to Fox News. “Number one: Iowa’s a democratic caucus. You ever been to a caucus? No you haven’t. You’re a lying, dog-faced pony soldier. You said you were; but now you got to be honest. I’m gonna be honest with you. It was a little bit confusing in Iowa.”

Biden had used the odd phrase last month as well to respond to a question about Barack Obama’s broken promises that Americans would be guaranteed the option to keep their doctors under the Affordable Care Act. He seemed to explain the origins of the phrase at a campaign event in 2018.

“As my brother who loves to use lines from movies, from John Wayne movies, there’s a line in a movie, a John Wayne movie where an Indian chief turns to John Wayne and says, ‘This is a lying, dog-faced pony soldier,'” Biden said at the time.

Moore said after the event that Biden was right in surmising that she hadn’t been to a caucus.

“I felt he did give some good answers,” Moore said. “It was a little awkward being put on the spot. But he was right. I haven’t been to a caucus. I kind of caved in the moment. So he’s right. He’s right there. But he’s right about the black vote, too. I mean, it’s very important. And the results have shown that people think he doesn’t have that support. So I’m still very skeptical, but I thought he did a good job answering.”

However, Biden has been widely criticized for the uncomfortable moment.

“If he can’t handle a simple question from one of his own supporters, how can Joe Biden possibly take on Donald Trump one on one for six months?” tweeted Donald Trump Jr.

This serves as a reminder that Biden is unfit for office, and really has no business even being in this race. He has made so many gaffes in the months since he began running that it’s impossible to deny that he would embarrass our country often as president. It’s time for Biden to save himself further humiliation by dropping out of the race once and for all.
