Joe Biden has plenty of go-to phrases on the campaign trail: "Folks!" "The fact of the matter is," and "Not a joke" are all favorites of the former vice president.
But nothing beats a good "C'mon, man" from Biden, the Scranton boy made good, who drops the classic, exasperated cry of the everyman whenever he gets a chance.
As theĀ Washington Post reported, Biden drops the term when he's expressing disbelief:
"China is going to eat our lunch? C'mon, man," he told voters earlier this year in Iowa.
When he's serenely confident, like when he assumed all Bernie Sanders supporters would vote for Hillary Clinton in 2016:
"They're all going to end up voting for Hillary. C'mon man," he said.
When he's disdainful, like when he talked about raising taxes $1 trillion on the wealthiest Americans in 2012.
"My heart breaks. C'mon, man," he said.
When he's defending his debate performance, like when CNN's Chris Cuomo wondered why he didn't stand up for himself more vigorously against Sen. Kamala Harris's (D., Calif.) attacks:
"In 30 seconds? C'mon, man," Biden said.
Biden is still the frontrunner for the 2020 Democratic nomination, but he has Harris, Sen. Elizabeth Warren (D., Mass.) and Sen. Bernie Sanders (I., Vt.) nipping at his heels.
We know how he'd respond if asked whether he was worried about the polls.
