Okay, today’s woke left hates him. But mainstream liberals didn’t hate him in the 1990s and 2000s.

Ron Klain (as portrayed by Kevin Spacey in “Recount”) certainly appeared to HATE Lieberman. And I would consider Klain as a mainstream liberal.

Also you are conflating two very different eras. Yeah, in the 1990s liberals liked Lieberman but after the 2000 election they blamed LIEBERMAN in a big way for the loss. And in the 2000s mainstream liberals made their final evolution to WOKE (and loony).
