I'm not sure that there are many traditional left wingers in America except for Noam Chomsky, who has always been politically marginal, and who is 96 years old.
Their tin ear was on display at Kash Patel's Senate hearing the other day. Amy Klobuchar is one of the few Senate Democrats who can still speak the vernacular of the New Deal Democrat, and might have been a better VP for Biden than Harris was.
But stick Kash Patel in front of her, and Klobuchar, knowing that Charlie Kirk was a friend of Patel, can barely squeeze out a passive-aggressive "sorry for your loss" before wanging on about how right wing extremism is the main threat and left wing extremism is definitely not a thing. Even Klobuchar, who's one of the smarter Democrats, really can't read the room.
Don't get me started on Cory Booker, whose addiction to ham acting is such that, if politics doesn't work out for him, he could have a career in Christian movies.
