What's the first thing a Democratic presidential candidate should do after suffering a monumental defeat in the first caucus of the season?

If you're Joe Biden, call a woman who introduced herself as "Madison" a "lying dog-faced pony soldier" after she says she's attended a caucus.

After a New Hampshire voter asks @JoeBiden why they should trust he can turn his campaign around, he asks if she’s ever been to a caucus before; when she says yes, Biden snaps: "No you haven’t.

According to Yahoo News' Sharon Weinberger, Biden has previously used the phrase - from a John Wayne movie - to disparage Republicans.

So, apparently Biden has used this "dog-faced pony soldier" phrase before, but about Republicans. It's allegedly from a film where an Indian chief tells John Wayne: "This is a lying dog-faced pony soldier."



However, haven't been able to verify that line. Any John Wayne experts? — Sharon Weinberger (@weinbergersa) February 9, 2020

Sunday's outburst is the latest in a string of Bidenisms - which have included calling a voter fat and challenging him to a push-up contest or an IQ test.

Joe Biden called Elizabeth Warren an elitist, but here he is insulting a man's weight ("sedentary" and "look, fat") and challenging him to an IQ test. Who's the real elitist here?

The clip was reminiscent of Biden's failed 1988 run for the White House, in which he challenged a reporter to an IQ test.
