Massachusetts Sen. Elizabeth Warren is fond of calling Donald Trump a "small, insecure money-grubber," deploying the phrase in tweets and during campaign appearances alongside Hillary Clinton.
More recently, President Barack Obama got in on the name-calling, referring to Trump as "a demagogue" during his keynote address at the Democratic National Convention on July 27.
And then there's Trump himself. The GOP nominee has a name for just about everyone, from "Crooked Hillary," to "Lyin' Ted Cruz" and "Low Energy Jeb Bush." He also calls Warren "Pocahontas" after the daughter of a historic Native American tribal chief -- a reference to Warren referring to herself as a Native American throughout her academic career.
But the one person in the 2016 race who says he won't get involved in the name-calling? Trump's vice presidential running mate, Indiana Gov. Mike Pence.

Pence abstains from name-calling and negative campaigning, a personal preference Trump apparently respects. The New York businessman told "60 Minutes" that Pence doesn't employ ad hominems "because it's different for him," according to NBC News.
On July 29, one day after Clinton accepted her party's presidential nomination, Pence reiterated his stance during an appearance on conservative talker Hugh Hewitt's radio show. He also criticized Obama for involving himself in the mudslinging.
"I don't think name calling has any place in public life," Pence said. "And I thought that was unfortunate that the president of the United States would use a term like that."
Pence swore to never engage in negative campaigning again after his failed 1990 bid for congress turned into what Mother Jones calls "one of the nastiest [races] in Indiana history." The next year, he wrote an essay decrying negative campaign tactics.

"First, a campaign ought to demonstrate the basic human decency of the candidate," Pence wrote. "That means your First Amendment rights end at the tip of your opponent's nose -- even in the matter of political rhetoric."
