Nearly four years after her historic loss to Donald Trump in the 2016 presidential election, Hillary Clinton continues to blame shift for her campaign's failures.

This time, Clinton has placed the responsibility on Sen. Bernie Sanders (I-Vt.) and his devout supporters.

"All the way up until the end, a lot of people highly identified with his campaign were urging people to vote third party, urging people not to vote," Clinton said on the "Your Primary Podcast" last week, according to the New York Times.

"It had an impact," she claimed.

The former secretary of state went on to contrast herself and Sanders, slamming the Vermont senator for not unifying Democrats in 2016 while claiming she supported Barack Obama's presidential campaign when she lost to him in the 2008 Democratic primary.

"So fast forward. I mean, you had, unfortunately, a very different outcome in the 2016 primary, where I won by 4 million votes. I won overwhelmingly in delegates," Clinton said. "There was no question about who was going to be the nominee."

"But unfortunately, you know, his campaign and his principal supporters were just very difficult and really, constantly not just attacking me, but my supporters," she added.

As the 2020 Democratic primary kicks into high gear this month, Clinton has been on a one-woman crusade vocalizing her opposition to Sanders.

Last month, Clinton confirmed her anti-Sanders feelings in an interview with The Hollywood Reporter when asked about the upcoming Hulu documentary on her failed presidential campaign.

"He was in Congress for years. He had one senator support him. Nobody likes him, nobody wants to work with him, he got nothing done. He was a career politician. It's all just baloney and I feel so bad that people got sucked into it," Clinton said of Sanders in the documentary.

Fortunately for Sanders, Clinton's opposition does not appear to be swaying voters.

Internal data released by Sanders' campaign showed he is likely leading the Iowa caucuses, which would confirm recent polling data. However, the Iowa Democratic Party has yet to release official caucus tallies.

Clinton's list of excuses on why she lost in 2016 includes Russia interference, racism, former FBI Director James Comey, the media and WikiLeaks, and voter suppression. She was also accused of running a flawed campaign, which included being under investigation by the FBI for using a private email server during her tenure as secretary of state and failing to recognize the amount of support Trump had in key battleground states like Pennsylvania, Michigan and Wisconsin until it was too late.
