Warren is fine, she is a sensible person. Bernie is not a madman but he will struggle with the partisan roadblocks.
What is going on is the right is being fed a constant barrage of the "radical left" is xyz, half made up, the rest wholly exaggerated. So Bernie is "pre-communist" and somehow by a magic trick Warren now may as well be. Warren's pro regulated capitalism and pro-middle class is exactly what being a conservative used to mean before the madness con machine of Roger Ailes' little projects started after Nixon, talk radio and Fox.
But hey, the guys can keep berating an empty chair like Clint all they want but I assure you, the imaginary leftist is nothing like the majority of real people.
