In a jab at former Democratic (and Independent) lawmaker and \u0022corporate shill\u0022 Joe Lieberman—who has continued to lobby for powerful private interests after leaving Senate just as did while serving in the body—Rep. Alexandria Ocasio-Cortez (D-NY) responded to his criticism of her brand of progressive politics by indicating his total irrelevance to the Democratic Party\u0026#039;s future.Cleverly, she did so by feigning not to know who Lieberman even was. \u0022Who dis?\u0022 she joked in response to a tweet highlighting a Fox News story titled: \u0022Ocasio-Cortez Isn\u0026#039;t the Future of the Democratic Party: Joe Lieberman.\u0022New party, who dis? https://t.co/2cznisv8tB— Alexandria Ocasio-Cortez (@AOC) January 11, 2019\u0022With all respect,\u0022 Lieberman told Fox\u0026#039;s Neil Cavuto on Thursday, \u0022I certainly hope she\u0026#039;s not the future and I don\u0026#039;t believe she is.\u0022But, the congresswoman wasn\u0026#039;t the only one to note the political irrelevance of someone like Lieberman:lots of tears from joe lieberman because he\u0026#039;s virtually 100% irrelevant in today\u0026#039;s democratic party pic.twitter.com/PeYWN4bB9l— Waleed Shahid (@_waleedshahid) January 10, 2019Ocasio-Cortez\u0026#039;s swipe at Lieberman comes as Politico reports Friday morning on the existence of a vague \u0022effort\u0022 by Democratic Party members to see if they can get the newly-elected (and very popular) progressive to \u0022play ball\u0022 by toning down her criticisms of the party\u0026#039;s established elite.\u0022I\u0026#039;m sure Ms. Cortez means well, but there’s almost an outstanding rule: Don\u0026#039;t attack your own people,\u0022 Rep. Emanuel Cleaver (D-Mo.) was quoting as saying in the article. \u0022We just don\u0026#039;t need sniping in our Democratic Caucus.\u0022Luckily for Ocasio-Cortez, that caucus no longer includes corporate lobbyist Joe Lieberman, who has enjoyed being both a McCain-Republican and a Trump-Republican during his retirement from public service.
