South Bend Mayor Pete Buttigieg on Thursday tried his best not to directly attack the 2020 race's frontrunner, former Vice President Joe Biden. But he did offer some criticism of his record and argued that he hasn't earned the nomination just yet.

Buttigieg during a live interview with The Washington Post was asked about those who say that Biden has "earned the nomination" because of his experience, to which Buttigieg rebutted, "I think you earn the nomination by winning it. Nobody's earned the nomination in 2019."

He went on to say that to earn the Democratic nomination, each of the candidates must not only present a vision for the party and for America, but also prove that they can beat President Trump. He later cautioned that Democrats could "very well lose again" in 2020 if they're perceived as "replicating a system that let people down," although he insisted that he's "not talking about any one of my competitors" in particular.

Buttigieg during this interview also offered some subtle criticism of Biden's record. When asked if Sen. Elizabeth Warren (D-Mass.) was right when she said that the former vice president was "on the side of the credit card companies," Buttigieg responded, "I have a difference of opinion with anybody who favors credit card companies over consumers." He also criticized the 1994 Violent Crime Control and Law Enforcement Act that Biden worked on, and when asked if those who supported the bill should be held to account, Buttigieg said, "that's what elections are for."
