Rep. Alexandria Ocasio-Cortez is used to getting heat from Republicans these days, but Democrats are typically far too afraid of her to challenge the young congresswoman on her radical far-left policies. That’s why it came as a huge surprise to her when former Vice President Joe Biden let lose on her during a recent interview.

The Daily Caller reported that Biden, who is running for president in 2020, said that liberal darlings like Ocasio-Cortez are far too radically leftwing to actually win over voters in a general election.

“I think Ocasio-Cortez is a brilliant, bright woman,” he said. “But she won a primary. In general election fights, who won? Mainstream Democrats who are very progressive on social issues and very strong on education, health care.”

“Look, my North Star is the middle class,” he added. “When the middle class does well, everybody does well.”

Biden went on to say that when it comes down to it, the Democratic Party is relatively moderate.

“Look, it’s center left, that’s where I am,” Biden said. “Where it’s not is way left.”

This comes weeks after Ocasio-Cortez spoke out to slam Biden and beg Democrats not to nominate him, describing him as “not a pragmatic choice.” The Washington Examiner reported that AOC went on to say that he would appeal mostly to voters who would otherwise support President Trump, which to her means white voters.

“That’s my frustration with politics today, that they’re willing to give up every single person in America just for that dude in a diner,” Ocasio-Cortez said. “Just so that you can get this very specific slice of Trump voters? If you pick the perfect candidate like Joe Biden to win that guy in the diner, the cost will make you lose because you will depress turnout as well. And that’s exactly what happened to 2016. We picked the logically fitting candidate, but that candidate did not inspire the turnout that we needed.”

Ocasio-Cortez is of course referring to the fact that back in 2016, Hillary Clinton was the person Democrats felt was their best option in reaching moderate voters. Like Biden, Clinton was a career politician who had been in the game for a long time, but voters instead decided to go with something different and pick a non-career politician in voting for Donald Trump.

This all serves as a reminder of how divided the Democratic Party is right now. If they don’t get their act together soon, they may just get Trump reelected in 2020.
