Democratic presidential hopeful Sen. Bernie Sanders' supporters are crying foul after former Vice President Joe Biden's Super Tuesday victory.

The Vermont senator took the clear lead in the Democratic race after the first three primary contests. But Biden has re-emerged as the front-runner after his Super Tuesday performance — in which he won a majority of the delegates — that followed his blowout win in South Carolina.

Now that Biden is back on top, Sanders' supporters are voicing their ardent frustrations and theories that the Democratic nomination is being stolen from Sanders.

For example, Marianne Williamson, a former 2020 Democratic candidate herself who has since become a surrogate for Sanders, claimed the Democratic Party has initiated a "coup" against Sanders.

"Jake Tapper referred to the 'resurrection' of Joe Biden's campaign. This was not a resurrection; it was a coup. Russiagate was not a coup. Mueller was not a coup. Impeachment was not a coup. What happened [on Super Tuesday] was a coup. And we will push it back," she said in a since-deleted tweet.

Meanwhile, Carlos Maza, the progressive commentator who led the charge to de-platform Steven Crowder, blamed the media.

"It's easy to blame Warren for this, but the bigger culprit is cable news, which treated South Carolina like a major unexpected comeback for Biden and likely had a huge impact on last-minute voters worried about electability," he said.

And then there was Cenk Uygur, founder of the far-left YouTube channel The Young Turks, who had a complete meltdown, lashing out at the Democratic "establishment" for Sanders' lackluster Super Tuesday showing.

Because it appears that Sanders and Biden will be extremely close in delegate count at the convention, the likelihood of a contested convention is increasing.

A contested convention would be bad news for Sanders, even if he goes into the Democratic National Convention with a slight edge over Biden. That's because superdelegates have much more power in a second ballot at the Democratic convention and would likely lean heavily in favor of Biden.
