A Democratic "campaign veteran" told the Daily News that "it's not a great look" for Ocasio-Cortez.

So no, I don't think Lieberman exactly has his finger on the pulse of the Democratic Party but it's cute that Fox is letting him play.
"She's new here, feeling her way around", Rep. Kurt Schrader (D., Ore.) said.
And she is expected to loudly advocate for Democratic primary campaigns against some of the middle-of-the-road members of her own party in Congress.
The New York democratic socialist would be a thorn in the side of Wall Street, which has seen its regulatory burden lowered since Donald Trump became president.
"Just as congressional Republicans constantly withhold criticism of the president out of fear he'll unleash a tweet at them, some Democrats have done the same with Ocasio-Cortez", Politico reported.
